First experience was a good one.
I'm a beekeeper, and although I never intend to get stung, it happens. Took what would be considered a light sting (I know, most people would never consider any bee sting "light", unless you're a beekeeper. Then, you know what I mean.) Immediately, I whipped out the pen and applied it to the spot. Then, I put the pen away and went on with my work. It wasn't until much later that I thought, "Hey, I don't have any swelling or itching where I got stung." It's the only time I've used it, and my first impression was positive. It is early in the season, and I know I'll get another chance to use it. If my opinion changes, I'll update this review.<br /><br />Update: Am really impressed by how well this works on my bee stings. Granted, there is some research that shows that beekeepers can build up a resistance, but using this has significantly cut down on swelling from stings. I've found I need to use it about four or five time immediately after a sting for it to be fully effective.<br />Update2: Tried it on a mosquito bite for the first time and worked like a charm.<br />Update3: If I had one complaint (not enough for me to remove a star), it doesn't hold a charge for very long. If I haven't used it for a couple of weeks the battery is depleted.<br />Update 4: Doesn't hold a charge for more than a day (took away a star).
