I was so excited! I could care less that it's a keychain, I just like having one that is small to carry in my purse. It's definitely an improvement over the larger one I had been using, it tended to weigh things down if I had it with me. I can't tell you how many times since I broke my old one that I've been somewhere and went to get it out of my purse, and it wasn't there. :(
It is the same length, just a little wider. That's okay, I have noticed it tends to stay in place better because of that which is important when you are trying to measure something by yourself. And, it was only $4! They had another one that was some sort of generic, it was $1, but it definitely didn't feel as sturdy as this one. I'm actually thinking of going and picking up another one so I can always have one in my purse, plus it would be a backup in case one of them breaks. Thank you Home Depot!!! You made my week.
