I have not found a Huma regulator that I don't like. This is just as good as the rest.

Product works great and is machined beautifully. I ordered from the United States and was very surprised on the speed it was delivered. When I received my order which had multiple items they had accidentally sent one of the wrong items however I notified them and they immediately sent me the correct product. The customer service experience was excellent, something you don't see enough of these days.

Awesome completely changes your hatsan bullboss. The numbers are consistent and accuracy improved by a clear amount. Can’t wait to bring it out to hunt Alaska! Definitely ordering another Huma regulator for my spare air cylinder!

I bought this regulator for my Bullboss in 25cal and it works like a charm. The difference between 22 fullpower shots is under 2ms. The accuracy of the gun has improved dramatically. I will absolutely buy this reg for my next hatsan rifle. Very easy to install and adjust. Fast delivery to Sweden. I recommend Huma in all aspects.
