You won't be disappointed.
Was not sure if this would work or not but it has been awesome. I know, weird word to use to describe a hose with 4 clamps on it, but, when it keeps the stinky stuff in the pipe and not on the ground and was pretty easy to install even in 45 F degree weather, that is awesome.

Good fir
I used already 3 piece,all of them worked perfectly on the pvc 4" sch40 pipe. Nice shield,easy to adjust the tightness and stainless steel. What i don't like about it, I feel little bit thinner the rubber what you can buy in big box store,but yes,is much cheaper. I hope last long term.

Great value. High quality
I absolutely love these. Unlike some we use from the supply house, it’s actually easy to start the clamps in the worm gear mechanism. They seem to be high quality and we haven’t had any leaks

Having used many different clamps of this type, this one is not well made or refined. Given the important of such an item, keeping your drainage system water type and sewer gas free, and often, once completed, the drywall is closed up and painted and you can not monitor its success or slow failure. It arrived beat up and deformed because of poor packaging. Just loose in a bag it has clearly been crushed being at the bottom of a pile. But also the rubber is not well formed. It uses 5/16 nuts to tighten, to a recommended torque of 80 in pounds. Every major maker of these clamps uses 3/8 bands and recommends 80 in pounds, but 60 inch pounds for the smaller versions that do also use 5/16. Something doesn't add up. I would not use this fitting behind a closed wall where it can not be monitored.

This thing is very light duty. It is 1/4 of the thickness of a fernco. It is not where near as good as a fernco. Not even remotely close. Do not use this in underground or in closed wall applications! You’ve been warned.
