I have really mixed feelings about this product. In some ways it is fantastic, in others, it is disappointing.
I have been using this for a while now and I must say that as someone who has suffered with lower back problems and tried a number of different massagers, this has been one of the best as easing my back and really working deep into the tissue.
Being able to strap it around my waist is wonderful, as it keeps it in one place until you want to move it round or up or down to massage another area.
I also found it useful for massaging my thigh muscles, although with this use, you have to hold it in place, rather than using the clip to hold it.
The design is not without flaws - for example, it must be connected to the mains via with the electric cable, which means that you are limited in the distance you are from an electrical socket and should you decide to get up and move position - you have to remember that you are impeded by the wire to avoid tangling yourself up. If only it could retain a charge for a short period, it would make it less cumbersome to use.
It has two sides - on the one side, the moving parts, which also heat for the most intense massage and on the reverse a knobbly side, which is suitable for more sensitive areas as it only vibrates.
I have found it quite awkward when trying to get the massager onto my back as the two sides are not evenly balanced - the more powerful massaging parts are heavier and so when you put put it behind your back it is quite difficult to get the part to remain horizontal, instead, aided by gravity, the heavier part is pulled down to face the floor.
It really is an effective massager, but it's design flaws mean that it can be a bit frustrating.
