First up,a big thanks to the Team at BlasterTECH, great,friendly staff and service.I purchased several Worker blasters and this ZWQ S100S,really wanted an orange one, but only 'clear ' coloured left,so I painted the interior surface matt black,this leaves the exterior surface bare plastic,so it a bit more durable.I struggled a bit with the build,as it comes completely dismantled,there is a heap of tiny parts an screws/nuts,but if you take your time it's a really satisfying projects Bradley Phillips YouTube videos on the s100s are excellent and really helpful,so I got the initial known air seal problems sorted during assembly.I won't lie, I had it apart several times to get it working right,the plastic block that holds the charging handle,is easy to break,when you fit the big self tapping screw to attach it on the push rod,I broke mine,so I molded a M5 brass screw an nut which is a much stronger set up.It's not a quick build,but once she's assembled it a really solid rig, very smooth charging action and shoots really good. Although I spent most a day working on it,I'm really happy with the final result.The metal internals kit and a stronger spring will fix the few minor issues with the s100s, improving power and reliability.Overall though,for the BlasterTECH price,it's incredible value, and a solid shooter,just spend some time on the build and set up. Cheers Brendan.Victoria. Apologies for the long review

This is the only blaster IV brought that I hate, first assembly was fine and I actually got a good seal out the box but that's when it went bad. Went to do a barrel swap n lost it, swapped orings n it was worse so changed everything back to original and was even worse, this is the first blaster I can not recommend as tuning n maintenance is rediculously effort n time consuming and whilst I love the look n feel of this blaster I want something that can perform and for the price I could get lots more reliable blasters that I don't have to go through the bull that this has caused, I'm actually giving myself a few days away from my blasters before giving it another go because I'm gonna break in half at this point, save your money and get a harrier, swift or Nexus pro because whilst the BAIZE has potential I don't think it's worth it when I can get better for cheaper.

The air seal is so bad darts get stuck in the std barrel. Even with the upgrade spring. I have used thread tape to pack up the seal grooves gradually to the point if being too tight. Even then air leaks from every seal area. I need thicker/better seals before I try anything else.

I brought this blaster and basically modified to begin with,due to the size of the plunger tube. The air seal out of the box isn't the best but a very easy fix. I got mine tuned at 280 to 290 fps, very consistent. I have gotten up to 350fps but hard prime, running 2 springs with the 550mm barrel. The build is not to bad and definitely watch out as there're many little bits,easy to go missing.. As a bonus it is lighter then a Swift and highly recommended, great blaster.
