This is a great product. It is firm as a rock. I have tested it using my 22kg weights and it succeed well (just 22 kg because I have not more :) ). I also have the 52mm(I bealive it could hold 30kg easily), but it is unnecessarily big for my purpose, so I got this 44mm smaller one and it just fits perfectly. I want it to hold my PCP rifle.
good qualty
