Watch the video do a dry fit so you put the sticky tape in the right place. Be sure to clean the tile. Have had no problems with this shelf. Holds full large bottles Shampoos & soaps. Looks great has handy hooks. Easy to clean once installed.The adhesive did not work very well so I decided to use the drill, so far so good. The color is like a black matte which goes well with my shower.?It's nice product and I wish that little smaller size is available in this.Updated 04/20/2020: Gricol themselves responded back to me about my missing part and sent a replacement. Install was easy (took maybe 10 minutes to clean, measure and level the parts) and I tested out the shelves this morning and they don't feel like they are going anywhere! They are much more sturdy than the other corner shelves I purchased in the past. I am happy with the product and it never hurts to reach out to the seller if something went wrong during shipping. Still giving a 4-star because the logistics issue should not have happened in the first place but appreciative of Gricol's efforts to fix my concerns.04/07/2020: I researched corner adhesive shelves via Amazon for several days before landing on these ones. I received the package earlier than expected but was provided a poor product and does not fit the advertisement.What I provided to the seller as feedback: "The nail-free stickers that are provided with the product I received are not as described either in the instructions nor on the advertisement. I was provided "hooks" that do not fit with the product and I, therefore, cannot install nail-free. Please advise." Pending response.I was looking for a not so permanent solution for my showers. These looked promising! I did read the instructions and it did say not to install the strips while attached to the shelf. But I didnt want to mark on my white tile so I went ahead and did it my way. I of course immediately regretted it because there were air bubbles from not being installed properly 100% my fault well about a week later the shelfs have fallen. I'm not surprised. I came on here hoping I could just buy new adhesive strips but I can't seem to find them :( frustrating because i really dont want to buy more shelves when i have two that are perfectly fine. I tried finding a way to contact the seller but I may have over looked it. If there ever becomes a way to purchase the strips alone that would solve my problem. Learn from me and install them properly and you'll have great long lasting shelves. I did give it a 4 star rating for the fact I'm not able to purchase more strip. I hope the seller sees this and is able to make the strip available for purchase in the near future.Easy to clean, easy to put up. And sturdyI think these shelves are wonderful.I was sure to read the instructions fully, but I had one problem that was not easy to understand in the instructions.There is one part that says.."Mount the stickers on the shelf for initial fixation.(do not lean on the innermost)"That is strange wording and it wasn't until after I adhered the stickers, waited 24 hours, and then tried to attached the shelves that I realized what it meant.Because of my grout lines I had the stickers all the way toward the corner. When I tried to slide the shelves on it didn't work, because the stickers were now immovable, there was no angle I could get to have them slide onto the screws. No matter what I tried, I could not get the screws to line up with the slots on each side of the shelves at the same time.This problem is not easy to foresee.So, bottom line, when you line up the stickers, make sure at least one side is NOT ALL THE WAY towards the corner.Hasta este momento el producto a funcionado y no se ha despegado en este tiempo, si lo volvería a comprar, es muy práctico.ca fait deja plusieurs mois que c'est installer et sa tient toujoursI wanted a sturdy, attractive shelf for my shower without have to drill into the new tile. Found it!Hope it stays affixed on the long haulEl producto es muy bueno y es lo que esperaba.
