Product review (5 stars): Great, if you modify them slightly
These are good for the price.

The product can be made great with modification.  The included (and pre-applied) tape is high-strength, but its just not going to cut it for this purpose.  No sticky tape will.  I wish they would have no pre-applied it, so that I could have used it for some other purpose.  Not a big deal, I still sort of used it.

First thing I did was cut out and remove most of the tape.  I only left a half inch or so border.  I then scored the bare plastic (where the tape is now removed) with a knife.  Mark and tape the rectangle where you will be attaching this.  Score or scuff it and clean with alcohol pads.  Get yourself some 30 minute or longer cure epoxy.  Mix it. Fill in the the de-taped and scored space on the pads with epoxy.  Peel off the tape label.  Press and hold the pad to the surface of the fridge or whatever that you previously marked and taped off.  The sticky tape ends up helping because it will hold it in place well while the epoxy dries, and will also prevent it from leaking.  Wait the recommend time for cure of epoxy.  When cured, these will now (truly) be permanently attached and secure.  For the stuff I used, that was 24 hours.

Using this method, these are, ugh, never coming off...ever.  You can lift the whole mini fridge full of stuff using this product and there is no way these are coming off.  The beauty with this product is that if I ever decide to repurpose the fridge and not need to lock it anymore, its not a big deal.  The cable part is removable, and only the bases will remain.  You can hang a bottle opener or whatever from it.  Basically, you really cant go wrong by (truly) permanently installing these.

I would buy this again
