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

Useful item
Remove the adhesive tape and brush some contact cement on the piece before installing.

Okay
This doesn't quite replace the original in that it allows too much travel for the inside slider.

Served its purpose but inferior adhesive strength
The product was not an exact fit but, as another reviewer posted, I trimmed it to fit better. Biggest problem was in getting it to adhere to bottom rail. The adhesive strip that was attached did not stick well and came loose almost immediately after contact with water. Ultimately I purchased some epoxy for underwater marine use and that resolved the problem. Not great but got the job done.

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.

Didn't stick
Adhered for 4 days and then failed. Useless 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.
