I ordered the smaller 10l pressure pot from Vevor. It seems designed for resin casting but still has a paint pipe installed in case you want to spray paint. This gets in the way of casting. I think Vevor should remove it. I did - with an angle grinder. I couldn't unscrew it. The pot works fine up to 50 psi (which is high as I need to go). No bubbles in the resin. No leaks from any point on the pot either, so no need for the supplied sealant. For £114, this pressure pot is way cheaper than the competition. I didn't find any CE quality marks and I haven't tested the safety pressure release (60psi) but it works well. If Vevor supplied castors the price would be a little higher, but I think they could remove the paint pipe (as an option?) or blank off that fitting without a major cost and sell it for the purpose most purchasers will use it for - resin casting. It would be good if they supplied an adjustable caddy as well as the internal base plate. Overall however, I'm very satisfied.
