Ours is many years old and it was homemade. It will bend 1/4" without any problem, just take maybe 30 extra seconds. The guy who made it, showed me how to do thicker stuff, but usually that will be much larger projects, so I have the vendor do it for me. We use it several times a week and we bend an unreal amount of PVC with it.
Years ago, I made an enclosed clear acrylic box with enough room to fit two hands in. My wife used it to do her nails. When she clipped and filed, the dust and pieces would go all over, not anymore. In warmer weather, she goes out and it goes all over the grass after she blows it away.
We have all kindsa jigs made for various on-going projects.
