I bought this to combat dew on my telescope. I had been using a real hair dryer in my backyard where I have 120v power. When I head out to my dark site, I have no AC power, so this little guy was going to fill in. I have to say I am fairly dissapointed. I didnt expect 120V level of heat, but this thing barely warms up at all. It moves plenty of air, but it isn't really hot enough for removing dew, much less drying hair.

Pros:
Small
Light

Cons:
Not enough Heat!
