The quality of the product is very good. The valve is heavy built it's something that you get your money worth with this product in my opinion. I have some Nathan old cast P3's so can't wait to try the valve out on them.


Badddd *** valve

Definitely massive!!! Has a nice rubber coated handle and is HEAVY you can 100% feel the quality! Haven't tried HornBlasters house brand to compare to but so far I'd say this one was worth the investment totally realistic sound quality.
