Where to start with this product? It is easy to use.
And so beneficial to anyone with back and neck problems, I've have been using it since 19th of January every day and I can already feel the benefits of it. I have had issues with my back for the last 6 years with limited movement, to now even with just a few days of usage my flexibility has improved so much, so I would recommend this Invospa Massager to anyone.
