Exactly what I needed at a good price
Fit exactly how I needed it to, flexible enough I was able to get it in easily but not so thick or thin that it wouldn't bend or bent too much. Seems quite durable and a great value.

Good adaptor.
I used this to connect to a harbor freight table saw and then to my dewalt shop vac I got at costco. The flexibility is nice because it stretches a bit for a tight seal.

Good product if it is the exact size you need
Unfortunately, this didn't work well for me. I was hoping it would be more flexible, but it wasn't. It didn't stretch enough to get around the pipe I needed even though it was supposed to be the right size. It's good quality, as long as the fit is right.

Used for a different purpose
I actually came across this while searching for a rubber adapter to transition the 6” OD outlet on my Super Dust Deputy Cyclone to the 5” OD inlet on my Delta 50-760 dust collector. It was a perfect fit and is very well made so I’m sure it will be great for it’s intended purpose.
