Excellent product, but read the description carefully so you get what you really want . . .
I just got these today and have already used them to remove a tiny sticker; worked great.  One word of caution, I purchased this twin-pack not realizing that one is in a tube and the other has the key chain adapter.  I was not familiar with the product and expected that each would arrive with the adapter and in a tube.  I actually paid a little more than necessary because of this misunderstanding.  Had I realized it was either one or the other I would have opted for both with the keychain adapter, not because of the lower price, but simply because that keychain adapter is a feature I appreciate.  So, I still give it five stars because the error was in my not fully understanding exactly what the listing was saying.  The product is very high quality and works; I just wish the options were stated more clearly.
Rating: 5 stars
