Do not stick (but should) with a fix - see below.

Like others said... Stickers are supposed to stick. These did not at all.

Solution - use a little bit of rubber cement to adhere to the wall. Worked like a charm.

Still, stickers should stick...

Should be five stars because this is a very cool gadget...BUT...the oval plastic plate that the doubled sided tape is fixed to does not maintain contact.  It's as if it is too shiny and smooth.  The two sided tape that came with it continued to pull away.  Then we tried a heavy duty two sided tape, same thing.  Then heavy duty double sided industrial strength velcro.  Still fell off.  Next we added super glue between two sided velcro and plate to strengthen how it was glued and had it dry overnight.  So far this remedy has worked but we will see over time if it continues to remain bonded.

Peeling any two sided tape and fixing it directly onto the oval plate will not work.

The holder has major issues with being in a hot car with the mounting product supplied.  Every two sided tape literally slid off the back plate.  Giving it the benefit of the doubt installed it inside our home near our desk and the same thing happened.  That's when we decided to super glue the velcro to it.

Unless you are prepared to super glue some sort of two sided tape or velcro I would pass on this purchase.

Not bad for the price. Picked them up for my Camry. Toyota recommends cleaning the area of application first with "simple green" THEN with alcohol wipes. Once they're on that's it! If you peel it off and try to re-apply it all bets are off! You will weaken the adhesive bond considerably, and they will eventually fall off.

I purchased this stick-on soap holder because no one makes an over-the-faucet hanging caddy for soap only.  I read the instructions and installed it in my fiberglass surround shower, attaching it to one of the non-porous embossed tiles on the surround. it would not adhere properly and air bubbles were left behind the adhesive backing that couldn't be pressed out. I removed it and tried installing it again, but with similar results.  I was unhappy with the product and gave it a one-star review in this forum.

Since my original review, I was contacted by the company's owner and we worked for several days to attempt a solution.  it was at this time that I noticed that the embossed tiles were not, in fact, completely flat.  each tile had a very slight wave in the tile pattern.  the height of this pattern was probably less than 1/100 inch high, but high enough that the semi-rigid clear adhesive panel backing would not conform to the surface of the tile and was the cause of the air bubbles.

So my warning is that the intended surface MUST BE FLAT. The owner is going above and beyond what the average company would do after finding that it was my error in failing to observe the problem with my tile surface. He is sending me a new backing to see if by trimming away a portion of the backing I could get it to stick as designed.  That remains to be seen, of course.  But I am very impressed with his response to my problem.  he has also advised me that his engineers are working on an improved backing that will allow it to adhere to imperfect surfaces. so here is a company that listens to feedback.

Because of his effort I am changing my rating to a 5star.  it is a good product and it will be better in the future.
And thanks again to Ben at BC Trading

The manufacturer ruined a perfectly good wooden tray by placing a giant, nearly-permanent sticker right in the middle. The sticker wouldn't peel off cleanly, leaving a big white sticky patch on the tray. Good luck getting that off without marring the bamboo. Too bad really, it's nice tray. Terrible choice by the company.

The lenses are stuck together. Horrible. Fix that problem. -_-

this very useful. buy one and when the glue looses its stickiness, wash it off and use paper glue to replace glue.

Tried to reposition, and will not re-seal on one corner.  Otherwise OK.

Hold on the treads is quite light but effective. It loses its stickiness in a couple of years, so then you have to replace it. I'd rather have a more permanent solution and not one I have to redo so often.

Worked very well, but a few leaked and required a permanent repair using crazy-glue

They sometimes fall off. What I had to do was put a drop of glue to make sure they stay in place. After that they worked perfectly.

I bought this a while back (Oct 2015) and it stayed stuck on until 3 days ago when it just slid right off. Luckily the manufacturer says there is a lifetime replacement warranty so I am hoping they respond to this review to help me move forward with that.

I used extra glue to stick them on based on other reviews so I can't vouch for the adhesive. The ends of my chair legs are not flat so I'm sure they wouldn't have stayed on.
They work for me.

Sigh. I should have listened to the comments. I just kept thinking, maybe it won't be so bad. Maybe superglue might work. Its not worth the price to be honest. Fail.

Slips out of adjustment in the middle of a run and could potentially destroy your work.
