Works, until heat melts the glue

Lasted just over a year until 112 degree California heat wave melted the adhesive. Wish this was a true suction cup and not glue based. Might hold up better in cooler climates.

These are great, if you don't live in a hot environment.  Temps where we live are routinely in the 90s.  The glue has melted to the point where strips will not stay on the wall.  We used the large size on frames as small as 5x7, but still had a few fall off the wall and break.  We followed the instructions, exactly, but the glue melts.  I would use again in a more temperate climate because the ones that are used in rooms where there is occasionally AC have held up better.

Works perfectly. I recommend using a hair dryer on low setting to melt the glue for easy removal.

the piece used to remove the old screen are not durable, as you heat the seal of the screen and the piece is near the heat they begin to melt.

Summary: This works perfectly to control the plugged-in, always-on pendant light I installed over my kitchen island, but I can only give it 3 stars because it began to MELT from a 100-watt bulb!

I picked this because there aren't too many options for socket dimmers on Amazon and this one had the most prominent knob. In that respect, this product is good. The large knob is easy to grip, has a wide range of brightness settings, and fades smoothly all the way down to zero. Unfortunately, there is no tactile feedback (a click, or anything else) when you have reached the 'Off' position. The light just goes out. Minor gripe.

The reason I took off two stars: It's made from cheap plastic. I installed it in an open fixture (downward-facing bowl-shaped pendant) with a 100 watt incandescent bulb, and over time I began to notice the cheap plastic closest to the bulb socket was melting and warping. The packaging states that you can use bulbs up to 150 watts. That seems unrealistic and unsafe. This may be true with a standard table lamp with an open top lampshade, but I wouldn't risk it.

On a side note, the packaging states that this should only be used with incandescent bulbs, but I assume it'll work with any dimmable bulb.

EDIT 3/9/16: Since replacing the 100-watt with a less intense bulb, I haven't experienced any more issues with melting. Product still working as expected.

I bought this and had to return it after 1 day.  It worked perfectly and video was crisp and easy to set up on my phone, However,  It got so hot that the glue kept coming unstuck from my windshield and falling off.  Even in the cool garage. the camera got hot internally.  After the glue came off I noticed there is a metal heat sink right under it.

It wasn't until after purchase that I learned the adhesive required a 300 degree bake to cure.  The article I wanted to apply the epoxy to couldn't withstand that treatment. I managed to finish the job by overcoating with a liquid urethane, and fortunately the connections have proven reliable now that the urethane has set.  However, it wasn't the right product for my application.

Used in conjunction with Gorilla epoxy to repair a vehicle's rear center brake light (center high mounted stop lamp). The mounting tape helps hold the light housing in place while the epoxy dries. It's been about a week. The connection should be very strong. It's summer (days averaging 75F) and I think if this solution wasn't going to hold, it would have already started falling off again. My solution is probably overkill, but I don't want to have to deal with this ever again. I prepared the surfaces by cleaning them with denatured alcohol. Another type of glue had failed after about a week, which was the second repair, and, of course, the factory glue had failed. I'll update the review if this bond fails, but it's looking good. I would trust the Gorilla double sided mounting tape and epoxy solution for a fallen rear view mirror as well.

We live in Texas and the glue just cannot stand up to the heat here. We've lost both already and had these less than 4 months, and it's been a cool year here in Houston. The glue is just too weak.

The tape will work for a short while on my phone but if you have a hot day, say above 80 degrees, or you enter into a hot car, the adhesive loses its strength and no longer works appropriately.  I've taken the time to redo the job twice now and I'm looking for alternatives.  I used both this 1mm and 2mm variety and they have the same issue.  The product needs to be designed to withstand common high temperatures.  Please let me know if you have another product in mind that I can use!

Note: I originally used this for strictly screen replacement on the Galaxy S4 before I started using UV glue.  It did work adequately in that respect minus the loss of touch sensitivity in the center of the screen.  For the above, I was using the tape under the whole digitizer and this is where the tape does not work well. I did put tape generously in all areas under the digitizer but still, the high temperatures rendered the tape useless and the digitizer will become detached.  This was done on the Note 4 so perhaps this tape is not useful for large screen phones.

It works fine, for a while. This summer, the suction cup melted in summer heat. I have to wait until cold weather to attempt to scrape sticky gunk off the inside of the windshield, and I have to leave a rag under it on the dashboard to catch the gunk that's dripping off!

UPDATE: After I posted my complaint, the seller responded and sent me a new, modified model. They've fixed the cup and tell me that it won't melt. Excellent customer service.

Prior to my problem, I found the thing to be excellent, even for a large Galaxy S8+ with an Otterbox case, a super-large phone.

I used it on a broken turn signal on my bike.  So basically I used it on plastic. It worked great initially. However after a short time, I noticed what appeared to be white powdery marks on the spot I had bonded. A little while after that, it came apart at the place it had been broken initially.

So I bonded it a second time, and same result. I say it's not bad, but I was hoping for a much stronger bonding agent and frankly, it may not be able to handle the heat produced by my bike pipes.

Looks good, had to heat it to get the adhesive to work

Worked ok until it was in the heat and melted. I live in the central valley of Ca where it gets pretty hot and it's a hassle to remove each time. I used it until the charging port caved inside and couldn't use it anymore.

I loved the way it fits in my cup holder, however after one warm spring day, the glue holding the rubber cover on melted and was very hard to use after.

Star had a point that the glue had not held. Dont know if the glue had come loose due to heat or poor application. Sent item back.

Suggest patching multiple tubes. Once glue is opened, does not keep well over time.
