I thoroughly cleaned the surface with alcohol and then attached the strip securely, but by the next day it was already falling down.

IF you apply it to the right surface and ensure the wires connected to the end of the strip are supported so they don't try to peel the strip off.

This non waterproof version sticks well to smooth surfaces with the included backing tape.

By the way, the secret to getting these strips to stick well is to have an absolutely clean surface

CCT may be way off, check before installing-Double-sided tape is easier to remove from the LED strip than the tape backing itself, would not depend on it on less than perfect surfaces or environments

Glue doesn't stick on smooth surfaces.

I painted mine, and made sure to rough up the surface before applying the tape (fine sandpaper) to ensure the tape stuck.

Lights fell down there on a brand new flat smooth surface and would not stick to anything half the backing came off when peeling it off with the paper and did not stick to the light terrible product

The surface i installed on was completely smooth and dry metal cleaned with alcohol and allowed to dry prior to installation

Bottom line, I gave the adhesive every chance to stick to the smooth surface of the lamp fixture

I thoroughly cleaned the surface with alcohol and then attached the strip securely, but by the next day it was already falling down.

The strip attaches to smooth and clean surfaces with double-sided tape labeled as "3M".

I cleaned the smooth metal surface and dried it before sticking the leds to it

The chemical odor is terrible, so I suggest for outdoor use only, if you can find a smooth surface to install

Perhaps I didn't degrease the varnished surface enough, but now it is securely attached with some two sided 3M half-inch tape easily found at Ace Hardware.

Kitchen cabinet undersides are unlikely to be good mounting surfaces without some work, particularly if they aren't brand new and have accumulated some hard to thoroughly remove kitchen grime

It grabbed faster and after being pressed onto the clean glass surface stuck in place very well

I've never encountered a "3M-Minnesota Mining and Manufacturing Company" product ever fail or get gooey and release from a clean sold metal surface.

and you'll see it's still real sticky - the problem is probably the mounting surface

Bare aluminum is a pretty good sticking surface for the adhesive (clean it with rubbing alcohol fist), but paint looks better.

Cleaned the metal first with soap and water then with alcohol, careful not to contaminate the surface after cleaning

Clean the surface with alcohol befor you stick it and light it up.

The degree of stickiness of the tape could be better; even on a very clean, flat, oil-based painted surface, small segments of the strip can become unglued after sometime.

If the heat cannot escape from the LED they will burn out extremely fast so between the waterproof covering and wanting to place them inside frosted cover U

like it we will order more thank u jay soni

This is a very bright (daylight) LED light strip, which works really well as an under-the-counter lighting strip

Works as it is supposed to, pleased with the item

This strip is bright enough to light the room, I chose the waterproof for ease of cleaning as they are above the stove and even with a microwave exterior vent some frying vapor still rose upward

I am about to initiate a return even though I have cut the LED as per my desired configuration

I was able to make the shape I needed with connectors and everything worked as it should on the first go.
