First of all, I just want to say I LOVE this thing! I mainly use it on my boyfriend and he uses it on me for back massages. I have 5 of them to create my own little hot stone effect. It's incredibly easy to use; you just snap the little metal part, knead it, and then wait for it to warm up. It doesn't take an incredibly long period of time to get warm, and it stays warm for about thirty minutes or so. I've found that half an hour is a good enough time (especially if it's just for foreplay), but if you want to use it longer, it's probably best to have multiples like I do (only not use them at once) because when you boil it, you can't re-snap it to warm it up immediately, you do have to wait a little while, and waiting could kill the mood, so it's best to just start using another one when the 1st one reaches the thirty minute mark.

It's great to use with massage oils too (just wipe it down afterward)! I like to put on some mood setting music, light some candles, burn incense, put on some sexy lingerie, dampen his back, and use my hands to work his muscles then use the warm massager afterward. Ladies and gentlemen, you cannot go wrong with this! It's PERFECT for foreplay. You can pretend you're in your own little massage parlor (I have quite a vivid imagination, lol).

Also, for you ladies out there, this is great to use as a heating pad if you have really bad cramps or lower backaches (like I have sometimes). It is great to use for any sore muscle really if you need a heating pad. This is really a great buy; I think everyone should have one!
