A Review of the GS-H5 Bottom Coil Clearomizer



The creatively named GS-H5 from Fasttech is a bottom coil clearomizer tank. In simple terms, it’s a cheap, plastic protank knockoff.

So what’s so special about that?

Well, price for one thing. This little gem clocks in at only $2.55. Quite a bit less than your Protank.

But is it equal in performance?

In my experience so far, it is pretty damn close.

These have been out for a month or two now. I finally decided to tack one on to one of my many Fasttech orders. For $2.55, why not, right?

It was stuck in shipping hell in China all month but finally arrived the other day and I had a chance to whip it out and do some handywork on it. Out of the box, it is what you would expect from a BCC. Standard coil with silica wick + flavor wick, interchangeable heads and bottom filling.  Appearance-wise, it’s nothing to write home about. It looks pretty cheap and shitty in the pictures. I would actually argue that it doesn’t look that bad once you get it filled with juice and attached to a piece. It’s a poly-carb tank, so a far cry from the nice pyrex you get from a protank, but on the flip side you don’t have to worry about shattering it either.


The coil heads themselves are pretty similar. I didn’t notice much difference one way or the other.

Once I got this thing rigged up with a sick carto coil, it has been performing awesome and I’m flying through tanks with it.

Let’s break it down in pros and cons.


Cheap. For the price, you can’t beat it. Really. It is a solid deal at $2.55 shipped and I will probably pick up a few more here and there. Great for taking out drinking or something where you might end up breaking it or losing it before the end of the night.

Capacity. This beast will hold 3ml of juice nicely for you, which should last quite a while.

Color Options. It’s available in a variety of colors – I’m not really one for colored tanks, but if you are, then you will like these.

Protank Style. It works just like a protank, so if you’re already familiar with them then this should come second nature to you.


Cheap. Well, it looks the way it costs. It is a crappy plastic tank and pretty much looks like one. I think it looks a lot better in person, but it still is what it is.

Built in Drip Tip. It has a built in drip tip, so you can’t use your own. Some may find this to be an advantage. I personally don’t like it and I really don’t like clear ones because the condensation shows through.

Who is it Good For?

This is actually a great all around device. If you’re happy with stock Protank heads, no need to reinvent the wheel. This functions just like a protank, except way cheaper.  If you’re into rebuilding heads like me, it’s also great as it’s a cheap guinea pig piece.

It’s really a good all around tank for a super low price, so it’s suitable for just about anyone.

Do I Use It?

I’ve been using it since I phreaked it, and it’s been working great. I’m sure it won’t be in my rotation forever, I will probably end up giving it to a friend – BUT, I don’t see any reason why I WOULDN’T want to use one other than the fact that I have so many other pieces to play with and review.

Where Can I Buy One?

I got mine on Fasttech for $2.55 Shipped.  I have also seen them at Healthcabin.

The Bottom Line

Overall, it actually exceeded my expectations. I picked one up almost thinking in advance that I wouldn’t like it because it’s so ugly, but really, it is actually a nice tank. It was super easy to recoil, it holds a ton of liquid, looks halfway decent on my Chemisis and it costed less than $3.

I really don’t have anything too negative to say about it. It’s a solid little utility piece that you don’t have to worry about losing or breaking, and it just plain works.
