CR can have their opinion.
But for best value price and low maintenance functionality, I would buy GERBER again. And again.
Yes , I know they don't sell the low volume toilet I have any more. Not low enough!! The 1.6 gpflush.
And you go into a toilet showroom and there are Kohlers all over the floor.
So I went into the discount Winchester blvd. place across the tracks, "Cloud" , and asked about "these rare Gerbers".
Oh, you're done your research, the salesman said. We keep the other good stuff in the back.
We also wisely bought the Higher ADULT HEIGHT versus the common and bit lower Family Height. Sooo much easier for seniors to get up from! And kids can still use a Step. Our cat has no problem drinking out of the higher bowl.
I grew up with 3 sisters, so know how to use a toilet plunger and 4ft hooked metal tube, taped curve to prevent scratching,8ft by 1/2" flexible steel toilet snake with red painted wood crank handle !! We have had several American Standards and Kohlers. Even a Toxx !
Still, highly recommend a GERBER and buy only at a reputable discounter, pro shop like "Cloud" in Silicon Valley.
