Peace of mind on the double

There's very little substitute for having the right tools at the right time and not have to worry about other interfering factors. Has saved vacations and work trips many times.

Good Things

As usual, all meds are good. Only problem was what you call the surgical set. “ not for medical use “. Definitely not worth the cost. Didn’t match up to the quality of all your other products.
