This heart warmer is great for romance and for those sore muscles, this really gets me feeling good when my back gets thrown out. It is a great product and works well for what it is supposed to do. the product is a plastic-like substance which is pvc that allows the material to be reused after boiling. It is a soft, smooth material that has no odor. My body's muscles feel great after using this,there is another oil that you can get to go with this that is a warming gel. The heat starts right when you bend the metal tab in the middle of the product and slowly gets firm. Just boil this heart warmer to clean and renew the liquid in the middle. This product should be inside of a towel when in use because it does get hot.

I am very glad that I got this product, it is a very romantic warmer that functions as more then just a sex product. It is the same as a heating pad, for after a wild night or special time of the day. It is discreet without sound and can be used anywhere. We just recently used all of our toys at a hotel weekend and we both needed this to release some muscles.

This product has no scent, it is reusable, and it doesn't need batteries or a plug in so it can be used anywhere... even on the go. It is very cheap but durable, I truthfully love this heart warmer and wouldn't go anywhere without one. After use when you boil it, the outer layer gets flimsy and does feel like it will break even though it is safe and secure.

My girlfriend really enjoys this product too because it releases a lot of stress after a long day and gets her ready for a fun night together with this sensual heart.

I literally had to buy another to keep in my vehicle. No matter where I go I can use this if I need to.
