The title says it all really. You won't appreciate quite how big and heavy this massager is, and the "massage" provided is very rough - akin to being hit gently by small hammers and it is pretty uncomfortable.
The heat applied through the infrared pad is quite good, although it takes a long time to warm up, and gets too hot. There is no temperature control.
Although the heat can be applied with the massager, the unit does not allow you to use the heat on it's own, which is pretty disappointing for equipment at this price level.
Overall I didn't get on with this item, and it gets 2 stars for the infrared heat. The massager gets nothing.
