Ordered a Pomson 6000 back in late December once I saw the listing appear and finally received it on Tuesday (4/22). I've been corresponding with Plasticbruv ever since the date of order, and he has been wonderfully transparent and was giving me updates throughout the whole process of prototyping.
Extremely happy with the end result. A few notes to other buyers - I had to do very light sanding on the insertion joint of the tip as well as the lever to insert them smoothly. Additionally, there's a disconnected antenna that needs to be inserted into a hole of the middle piece, which will need to be glued in to remain permanently. Do not glue it in before you get the tip attached fully, as I imagine it'd be a bit tedious to work around after the fact.
As the listing states, it is fairly fragile so it's definitely not something I'd recommend being too rough with. The materials seem sturdy enough that I shouldn't expect too much damage from use in cosplay, though.
Treat this thing with greater respect than Valve has treated the in-game weapon and you'll probably be fine.
