Authentic 3M
I use these to fasten my Strymon Ojai R30 power supply underneath my pedalboard and it works wonderfully. Regular velcro was not strong enough for this application.

Strong and reliable
Like the title say they are decently strong and don't fall off of a flat clean surface. I always use ethanol alcohol to clean the surface instead of Windex as the latter could leave residue on the surface making the back adhesive not stick as well. For the price they are great .

Very solid grip
I have used this to attach a small LED tubelight under the cabinet. I have not done a long term test on this but used it for the last couple of months and the grip is very firm. The LED tube used to fall when I used some cheap Velcro tape earlier. But now for at least a couple of months it has not done that. A very useful purchase.

The locking works too good, the sticky no so good.
I thought these would be a nice step up from the classic velcro stuff. It take a lot of force to get the interlocking halfs together. And then to pull them apart ended up pulling them off the sticky side. I'd like to see less force on and off, and better sticky, then it would be great.

High Quality, very sticky
I bought these to mount my Ring Doorbell mount to my front door and it has held up to both freezing and warm temperatures with no issues whatsoever. Great product!!

So strong the adhesive doesn’t hold
They have such a strong bond, they can pull loose from their adhesive if you don’t remove carefully. I’d use these for permanent mounting from now on. If it’s something needing removal occasionally, I’d pick something else.

Really great
These are so strong they can hold nearly anything. The adhesive is strong and the grip is amazing. Use your imagination and see what you can use them for. I am very pleased with their performance.
