I love this product as it has really helped my back ache. I have had problems for 30 years and what better way to treat your back than when you are asleep. I have just ordered a 2nd one for my motorhome.
I bought two and loved these little torches until they needed re-charging. Quite simply they don't recharge AT ALL! Go for better quality. I can only assume that the positive reviews are from people before they have tried charging them with sunlight!
I bought this because of lumbar problems and it really helps. having shopped around the chair is great value and perfect for the job. Easy to assemble in about 10 minutes. Since I have bought two more for my wife and child who loves it!
