Fine Tool, No Instructions
The tool works as advertised; however, simple as it is, it would benefit from use instructions.

Good product for the price
What I cannot say is how long this will last: how many times it will work. If it poops out inna year or less as I use it, I WILL edit this review!

Simple, inexpensive, must have tool!
I purchased this last year, because it was mentioned on a podcast. I thought it was a must have tool, so I bought some more for inexpensive novelty Xmas gifts last December. They were such a hit, I bought several more for X-mas 2025. I like mine, and the giftees like theirs too. On the downside, I've bought so many that I don't know who all I have given them to. I'll have to come up with a different inexpensive gift for next year. I've been using mine for about a year and a half. I recommend it! I'll buy a couple of extras for ME to have in different places around the house.

It seems to work.
It seems to work. It looks good. I just put it in my small tool toolbox. If I am not satisfied in the future, I will buy something else.
