Kink Industries' Jail House Review and Questions

Has anyone here tried out the Jail House from Kink Industries? I’m leaning towards it because 1) the price is excellent ($100), 2) it’s made of metal, and 3) it has a nice appearance. The main drawback seems to be that it isn’t stainless steel; I’ve heard reports about it being susceptible to rust. Another concern is the fixed length/circumference, meaning it might run quite a bit larger than what you’d get for $290 with a Jail Bird from Mature Metal.

The Jail Bird remains my ultimate goal (I could afford it right now), but I’m curious if the Jail House serves as a solid option to experiment with while baby-stepping through chastity.

Thanks.
