The Thunderhead Creations Thunder Storm BF Mod is a very well made and great value for money PPS squonk box. It's similar in size to and has a better ergonomic feel over the Hugo Vapor Squeezer, whilst being only about 8mm taller. This one ticks all the right boxes. It accommodates 18650/20700/21700 batteries, spring loaded 510 pin, responsive firing action, very good silicone bottle and attys up to 26mm fit with no overhang. Having two separate doors for the battery and the silicone bottle is a good idea and the magnets on both are very strong so there is no chance of either door accidentally popping off. Some reviewers have said they had a problem with the firing button and that if you don't press it directly in the centre, it doesn't fire. Mine has the same problem but as the firing button is big and it's curved outwards you will rarely find yourself only pressing the corners with your finger or thumb. The locking feature also works very well. The only con I have is that it doesn't come with an extra silicone bottle or a 30ml silicone refill bottle like the Squeezer does. As soon as FT list the blue and red versions I'll definitely be buying them too. Highly recommended.

This 22mm single coil rda is just as good as the Entheon imo. Quality made, practically leakproof, top airflow, great flavour, easy to build on and includes a squonk pin. Great value and highly recommended.

These resin 510 drip tips are a little too tall for my liking and the tanks I had in mind for but the quality is good and they are reasonably priced. The colours are bright however you get random colours.

For under $15 this clone Boxer squonker gives you a small lightweight, hard hitting ABS molded and painted ergonomic box, with a lockable firing button, 8ml squonk bottle and clean internals and stainless steel contacts/connection plates. First thing you should do is replace the hard bottle with a super soft silicone bottle. The friction fit door slides into place easily but does not wobble around. You can add small magnets for a better fit. The battery contact plates are clean, have no sharp edges and will not chew up your battery wraps. The 510 pin is fixed and non adjustable. The body is painted so it will ultimately wear over time. It has a smooth texture on one side and a rough surface on the other side. Overall it's what I expected for the price and am happy with it.

This was originally listed as the Ulton version but it has since been changed to an unknown manufacturer. The machining quality and overall tolerances are still very good. It comes with logos on the base and 4 additional airflow plugs but no spare replacement tank. Like other Taifun products the single coil deck on the GT One is easy to build on and it's capable of producing a tight mtl using the 0.8mm pin up to a very rdl using the 1.8mm pin. The rta comes with the 1.2mm air pin pre-installed. I also found that removing the tiny pin next to the external airflow hole didn't change the draw but made it less quiet while still remaining smooth. Using a simple round wire coil or clapton coil flavour production and throat hit is very good. The top cap on mine was screwed on so tight that it took a lot of unnecessary effort to unscrew. Be careful when putting the tank back together because screwing the PC tank to the base and top cap can cause cross threading against the metal threads so lube up the PC threads with some e-liquid to minimize the risk of this happening. It's a bottom filling tank with no juice flow control so that may be a con for some people but I converted mine into a top filling tank with juice flow control using the SXK top fill kit which is available as a separate purchase. The only difference I see between this version and the Ulton version is the Ulton one comes with a spare tank and a green o-ring for more than double the price of this one, everything else is the same. Overall it's a very good single coil mtl rta, especially with the top fill conversion kit installed.
