Gave me more time with my treadmill.

I have a treadmill that's about 25 or 30 years old and well used. A hole popped up in the tread belt joint. I'm not ready to give up on it. I ordered this tape and so far it's working great. It's VERY sticky which is good, but once it's down it's not coming up easily which is why I gave 4 stars on ease of use. Try to put it where you want it the first time. I've lots left over as I only had to use about a foot or so. I would definitely buy this again.

Awesome product..!

Excellent product. 100% recommended..! I used it to cover the charging cable for my electric vehicle, and its level of adhesion to concrete is impressive.

I needed a waterproof tape that could be used outside. I have applied the tape and it is holding well and does repel rain. I knew since haveing used this tape in the past that it can be hard to place exactly in the position that you want, due to the fact that it immediately grips to the surface making it very difficult to reposition. Despite this issue, I am very satisfied with the product.
