Really good
This worked for our mid 90’s shower frame. Had to cut it down some on flat side so it would fit. Adhesive seems to stick just fine even though I saw some reviews that said it didn’t. Probably doesn’t stick as well to colored aluminum. We have the silver shiny one and it sticks like crazy

WORKS GREAT
Used for door glides on Sterling tub/shower door. Excellent product. Had to make one minor modification with a utility knife. Still great product, was perfect & worked exactly as advertised. Nor sure about the adhesion of the double-sided tape, added a small amount of adhesive caulk just to be sure.

Works good
It does keep my shower door in the track, but it's not long enough. I stuck it down with the supplied adhesive pad but that only lasted a couple days, so I had to drill some holes and screwed it into place. The screws get in the way of the door operating smoothly.

Not impressed — Temporary Solution only
Did not adhere to tub/shower. Opening to large, so door wobbles in track creating noise. This is a temporary solution while you find the correct slider.

Easy, Peasy
Great product. Very simple installation process. I wish it the adhesive sticker spanned the entire bottom of the divider; just for a truly confident fastening. It may have stayed on its own, but I used some additional tub surround adhesive to really cement it into place.Overall: nice, simple product.

Works well for a few days
This worked very well for a few days but the adhesive does not last and it just eventually fell off. I’d recommend buying one that can be anchored with screws. Water and adhesives just do not mix well.

Disappointed
The tape turned loose after a few showers. I had cleaned the area, then used alcohol wipes. After drying I stuck it down and didn’t use that shower for 2 days.
