Review on Gerber 99-647 PowerTool by Micheal Chaplain

Fool me once shame on you Fool me twice shame on me. I have purchased these dampers twice (8 total) as stock replacements for all 4 of my bathrooms. The originals didn't last 2 years before the edges started folding (all of them) and all the toilets started working constantly. Replaced them all AGAIN twice with the same part and they are all deformed again. I do not recommend this product and will try the standard Lowe's 2" replacement parts to see if they work better. Do not buy!
