So is This New Single Coil RTA Going To The Top Of The Class?

The Bachelor X is as the name suggests a single coil 25mm RTA from EHPRO.

The company has brought out some decent devices in its time including the Billow V3 Plus – the MORPH tank and the SPD A8 TC Mod.

So a company with a decent enough pedigree who’s products have on the whole been received well.

So how does the Bachelor X stack up and if this was vaping Tinder would I swipe left or right?

Let’s take a closer look.

The EHPRO Bachelor X RTA was sent to me for the purpose of this review and as always my thoughts and opinions are my own.

Inside the Box

A basic cardboard box that does its job lol.

Inside you’ll find:

  • X1 EHPRO Bachelor X RTA
  • X1 Bubble Glass Tank Section
  • X1 Allen Key
  • X3 Pre-made Coils and Cotton
  • Spare Part Pack
  • User Manual

Key Features

This is a single coil RTA with a 2 post gold plated dual terminal deck.

The coil legs are held down by hex screws – something I’ll certainly get into later…

bachelor x rta

Out of the box it’s 3.5ml capacity with a bubble glass tank that bumps it up to 5mls.

It features a huge air flow port on the centre of the deck and adjustable twin bottom airflow control.

It’s a simple enough top-fill with two generous kidney shaped fill ports and an 810 ULTEM drip tip – others I’ve tried do fit.

Design and Build Quality

Design wise it looks very similar to the Vandy Vape Kylin V2 especially in bubble glass mode with knurling on the top cap and the air flow control ports at the base.

Bachelor X and Kylin

The central chimney has a mortar board etched into it – the type scholars wear when receiving their degrees and there’s Bachelor X engraved or stamped into the base on one side and EHPRO on the other.

bachelor x bubble glass
with bubble glass

It’s actually quite an unfussy clean looking RTA – however as looks go it’s let down by that hideous drip tip which of course can be swapped out.

It’s not a badly built tank either but certainly not one of the best I’ve tried.

Whilst all the moving parts come apart easily enough the materials feel dare I say a little on the budget side.

bachelor x components

I have the stainless steel version and it looks and feels thin in places and almost coated in a kind of chrome effect to add a bit of lustre.

A quick word about the O rings too.

They are thin – flimsy and have a habit of bunching up and as I’ll tackle during how this one performs – they aren’t the best seals either.

I’m sure from my tone you’re starting to get an inkling this one hasn’t impressed me and I’ll explain why.

How Does the EHPRO Bachelor X RTA Perform?

I enjoy a single coil RTA and RDA – indeed they are my ‘go tos’ in house and out and about.

I like the fact they are easy on the battery and juice and dead easy to build on – in other words you don’t need a Bachelor’s Degree in engineering to get up and running.

At first glance the EHPRO Bachelor X looks like yet another dual post single coil RTA that you can quickly pop a coil in wick – juice and enjoy.


Building on the EHPRO Bachelor X RTA

Probably the worst building experience I’ve had yet – especially using the supplied coils.

The way the post holes are designed means you can pop one leg in easy enough but to get the other in you have to completely remove the grub screw.

You need the skills of a bomb builder who trained as a Swiss watch maker to get that grub screw back in – something I haven’t got judging from my cursing and scrambling under my desk to find wandering screws lol.

bachelor x coiled

Little wonder EHPRO has supplied 4 extra ones – it’s almost as if they anticipate a lot of scrambling around on your hands and knees tracking down runaway screws…

I used the supplied coils – yes coils plural – as they’re so shoddy when I got one in it snapped whilst easing it over the airflow.

broken coil

I had to do some seriously gentle jiggling about with the second one of theirs I tried to straighten the kink in it!

Why EHPRO couldn’t have opened up two of the legs on the side like many other new RTAs out there – including the GeekVape Ammit – I don’t know.

Building on this was no pleasure for me – I’m sure plenty of you will say it’s a doddle but this is not one for those of you with dexterity issues – I’m lucky in that aspect but still found it a complete pain.

bachelor x coiled and wicked

On a brighter note wicking was pretty straightforward with the very generous wicking ports that are reminiscent of a genesis style RTA.

I have tried pre-cutting one of the legs and managed – in a fashion – to get it screwed down however the shoddy coil [could be just mine lol] snapped as I tried to iron out the kinks.

Maybe you’ll do better?

The O ring on the deck is also a bone of contention with me.

It is very thin and flimsy and does kink up at every opportunity.

I have noticed the seal between the bubble glass in particular is not so good and whilst it hasn’t flooded out – there is enough seepage to notice.

I have actually re-built this half a dozen times now and whilst I’m getting better – is it worth all the hassle?

Flavour and Clouds

OK first fill and using one of the supplied coils coming out at 0.27ohms and wicked with Fuzz – I wasn’t impressed at all.

75w airflow wide open and the flavour was washed away.

The flavour was muted even with the airflow half way closed – this is an airy tank.

wicks well

After fiddling about with the airflow and wattage I found – and I don’t want to say sweet spot – a passable vape at 77w with the airflow just over half closed.

Clouds were OK – nothing to write home about.

I popped in a new coil – eventually – a basic Clapton at 0.25ohms – wicked again with Fuzz and began again at 75w with the airflow open.

The flavour was slightly better as were the clouds – but again not in the same league as other single coil RTAs I’ve used such as the Geekvape Zeus – and Augvape Merlin Mini.

Up at the lofty heights of 81w the vape was again slightly better but again the flavour whilst there was struggling to fully come through – it was there in the background but definitely not popping.

So no for me the hassle wasn’t worth it for the resulting vape.


  • 3.5ml out of the box plus 5ml bubble tank
  • Not a bad design looks wise
  • OK flavour
  • Reasonable clouds
  • Easy to wick
  • X3 coils – let’s hope yours are better quality!


  • Needing to remove a grub screw to get the coil legs in
  • Poor O rings
  • Included coils a little ‘weak’
  • Included cotton not so good
  • Price – it is overpriced at the moment

Final Review Verdict

Given I’m a massive single coil RTA user I was hoping for big things from this decent looking single coil tank.

For me the farting about [let’s call it the Bachelor of fARTS] with having to remove a grub screw to get a coil leg in is a ridiculous design ‘feature’ in 2018.

But hey if you have a Bachelor’s Degree in deck building this will be a doddle for you…maybe 😉

The flavour is OK nothing amazing – and the clouds whilst decent are nothing to write home about – even at higher wattage.

I’ve just had a look at pre-order prices and this one is coming in at between $30 and $35 dollars which is way way too expensive for what you’re getting IMHO – so another downer lol.

Not for me when there’s far far better alternatives out there – but then I didn’t get a degree – only O Levels 😉

Note: after writing this I found a review from over the pond by a reviewer with a huge following.

He absolute loves it – lol – and called people who might not like the need to remove a post screw to get a coil in ‘nit picky’.

As we British say…

Bollox – these days we shouldn’t have to mess about removing fiddly grub screws to build on a deck especially when leaving x2 open sided would have made this accessible to all not just those with the dexterity of a brain surgeon.

But hey that’s the beauty of vape reviews – mostly – or as the Devil Vaper says with a twinkle…apparently these days in some quarters when it comes to new vape stuff…“everything is awesome…”;)

I have simpler vape tastes these days - I never leave home without a Caliburn G, a Vaporesso Luxe 40 or Innokin EQ FLTR and a CBD vape pen or bottle of CBD drops in my rucksack...or indeed an Aspire Nautilus Prime X in my pocket... At home I'll be using various mods topped with the GeekVape Zeus X RTA or the Signature Mods Mono SQ topped with the Augvape BTFC RDA... I'm a former journalist and now a writer and sometimes author... I'm ex Army - adore dogs and never happier than hiking over the hills or with a good book on a beach.

ehpro-bachelor-x-rta-reviewSadly this particular bachelor just like me is destined to remain on the shelf...flavour just OK but building on it did my head in...


    • As I always say it’s best to read/watch a few reviews to get an overall view of any device. For the record and after a few positive reviews out there I brought it back out as I was intrigued… Using Contra which is hardly the most acidic juice out there the glass was cracked within a day. So I bought yes bought another and again using Contra the glass cracked within a couple of days…so I have binned both of them…as to flavour – and obviously it could be my builds – I wasn’t that impressed…however that after all is only my opinion…Thanks for the comment – Cheers!

  1. Reading your review it seems as though you are lacking building skills. This deck is one of the easiest to work on. The grub secrew is not problem at all to get back in provided you use a decent hex key, which most builder will have. The flavour is great, if you build it right, and to be honest, it is difficult to build wrong. To anyone reading this review go check out The Vaping Postman’s review on YouTube. This tank is very good and this review does not do it justice at all

    • Yeah I am not the world’s best builder by any standards lol – well spotted. However my thoughts on the need to remove a screw to get the coil legs in makes this a fiddly RDA for very many vapers especially in this day and age – hence my downer on that point. I have persevered and after more than a few builds using my coilmaster hex key/driver it has got easier with practice. As to my mate Mark’s review [TVP] there’s many items he’s reviewed and disliked that I liked – horses for courses and all that 😉 Glad you’re enjoying the Bachelor – I did not 🙂 Thanks for the comment 🙂
