Great, super grippy tape. I use this to hold a somewhat large hotspot in place in my car. It firmly holds the device in place in an area subject to high humidity and large temperature swings. Yet I can easily remove the device when I need to. I also use it to keep a battery pack attached to the hotspot. One caveat: as good as the adhesive backing is, the grip is perhaps even stronger. So don't use it on drywall or other non-solid surfaces unless you intend to keep the item permanently in place.

A must have. Hold very well. Very useful when you want to avoid screws or nails like in a RV/Motorhome. Super fantastic product from 3M. YES recommend 100%

I have bought this many times and use it for rc car batteries to hold the battery in the car. The sticky part works well and the Velcro holds super strong!!!

I have been using this product for years. Before Amazon I got it from the iTape store. I have over a dozen ceramic tiles attached to the walls of my RV, all by Super Lock tape. None have fallen off after 100,000 miles.
