My ex gf bought me one of these a few years back when we were dating because she thought the name and look were hilarious. I tried it about 6 months ago and I have to say, it's really quite good.
It's pretty easy to clean, but not very easy to dry. Tends to stay damp on the inside unless you get creative in drying it out.
It can be used with or without the case, but most like it with the case.
It's best used warm and the suggested method of heating it is by submerging it in warm/hot water. I found that a flexible heating pad on a VERY low setting (it will melt otherwise) is the best way to heat it up, albiet much slower.
The end cap of the "light" is adjustable and allows for variable suction.
It comes in a variety of styles (as folks have seen) but also a variety of interior sizes and "sensations" for the interior canal. The wonderwave is the most popular choice for sensation. IMO it's the best. (yea, i own a couple of these now) I've tried the different interior sizes (i'm a wee bit bigger than avg) and found all of them to be fine, but the 1/2" size to be the best.
After trying it a lot of guys love these things, a few hate them. The maker runs a forum on thier website that has a lot of info if you are interested, however I believe they delete posts that are negative about their products.
The case does not really look like a flashlight, so don't think you are going to pop one in the toolbox and hide it from wifey.
You need to use a water based lube, my personal fav in that arena, astroglide, didn't seem to be the best choice for this thing and I wound up using a water based foam lube.
I thought long and hard
about making this post but WTF. I get it from a real girl on the weekends, and that is far and away the best thing going, but during the week, well, the fleshlight is there.
As for the orgasms? Yea, they are incredible. Beats Mr. Hand by a LARGE margin.
/hope that helps anyone considering a purchase
