Nice idea, and we have bought a number of slow close seats from various manufacturers. Unfortunately, our Delta experiences have now resulted in our last. The installation is very easy. Compared to other products though, I have a few gripes: - A product sheet is included, but no installation instructions. Admittedly I did notice there are installation pictures on the outside back of the packaging. I'm frustrated though because I look inside for instructions and see a "product sheet" listing 12 model numbers and a parts diagram where the 12 model numbers are listed yet the parts diagram doesn't list part numbers, and no explanation for what to do with two clear, flat, rubber pieces. WHY NOT KEEP THIS SIMPLE and have the correct model and part diagram for what I bought, with pertinent instructions on the same page? - I'm smart (LoL not observant apparently since I missed the instructions on the box exterior), so I quickly determined how to use the clear rubber parts. They attach between the seat and toilet to prevent the seat from slipping left/right on the toilet. This is a nice feature since a number of toilet seats slip bo matter how much I tighten them. - However, the nut and boldt used are inferior to other products. The underside of the toilet where the nut/bolts attach is convex. I very much like the new plastic nut/bolt system where the nuts are concave because they attach very securely inside the toilet convex opening. The supplied nuts are flat which means they do not seat securely in this area. - Likewise, the head of the bolts require a standard screwdriver. The depth of the area where the screwdriver is deep enough for installing but this bolt is made of plastic and the depth is not very deep. Historically this means you are more likely to strip the head when attempting to unscrew this on a later date. I much prefer the deep philips slots on the bolts provided by other manufactures. - After installation I tested the product. The lid stays up without issue but the seat immediately falls to the halfway point, then slowly closes :( I then opened both lid and seat at the same time, with the same result. Admittedly I did determine it was possible to raise the seat, hold it in place for a few seconds, and have it stay up. However, especially since I dont have thos issue with my White Cloud nor Mayfair slow close seats, nor any other toilet seat I've purchased in the last 30 years, I find this unacceptable. The seat itself has an attractive appearance and i very much like the reinforced bottom edging/railings for the seat. It appears to he a far sturdier plastic seat than thers I have inspected previously. As for those two clear rubber pieces, they definitely prevent the toilet seat from shifting left/right - except the seat and lid are loose enough with the section bolted to the toilet that they still can be jiggled left/right. Really? I know this is being nit-picky but COME ON how difficult is it to make parts/connections which are not loose? I checked my Mayfair slow close, and re-instslled my old seat, and neither of these have this issue. BTW I am replacing the old seat because the metal screws connecting the anchors to the toilet seat have been rusting, and it's not a slow close. On the plus side, I called Delta rather than return the toilet seat to Amazon and Delta is shipping a new seat (thanks). If it has the same issue though, we will return this and buy non-Delta. This is probably our last delta purchase. I recently bought a Delta Classic 400 tub with enclosure, as well as shower pan with enclosure, a long with a Moen and Delta fixture for the tub and shower. No issues installing the Moen, numerous issues with Delta. Way too many issues installing the Delta Classic 400 products. Should be very simple but those products aren't designed for sturdy, non flexing needs required in the bathroom.
