The only reason I didn't give this five stars is because nothing is perfect, or I haven't found it yet. But with that said, the is a very good, and extremely affordable, mech squonk.
The tolerances are very tight and everything thing has a very tight and nice feel to it. The squonk bottle is top notch. Far better than other squonkers I've purchased with the hard plastic bottles they they included.
I also purchased different colored side plates and an additional squonk bottle. Great for switching up the looks on the fly.
For the price I don't really have any complaints.
Great mod and a great price.
