WonderPax - truly wonderful! Found the WonderPax for back and shoulders a great help with my arthritic shoulders. So soothing, and so easy to heat - just a click needed, stays hot for ages, and afterwards just soaking in hot water to return to liquid gel again. I can't take anti-inflammatory medication, so these are an absolute boon. My daughter has a Pax for her back, also a couple for her hands to warm them up for Archery in winter! Also can't fault the customer service.

Do NOT like the product due to the reheating method!!!! Purchased the neck & shoulder and also hand warmers from the RI home show.... The sales people were VERY aggressive! That should have been a warning right away. They should have explained how the items need to be reheated. If I had known how it had to be done, I would have NEVER bought them!!! They need to be put in boiling water to get them to heat up. Too much opposed to popping an item in the microwave!!! ie: how are you supposed to rewarm the handwarmers (lets say at a ballgame), carry around boiling water???

Customer support service: I was very impressed with the support and quick response I received from Eddie, at Clix Therapy, when I contacted about a fault with the neck and shoulder Clix I brought. He assured me of the guarantee of the product and I was very happy to receive a replacement. I have been using Clix Therapy products for a number of years and have also bought them as gifts for others.

I had a problem with a back and knee… I had a problem with a back and knee pack that my Son bought me for Christmas, emailed customer service and straight away they responded and said they would send me another one. However after 2 weeks when it didnt arrived I emailed them again and Eddie apologised and sent me a another one plus a free gift no questions asked even thought dpd sent them proof of delivery. Two days later dpd found and delivered the original one. I cannot recommend Clix Therapy products enough and their customer service is excellent.

Replaced my item quickly I purchased a back and knee pack from a vendor at an RV show in Dallas, after my first time using it as a hot pack I placed it in boiling water and unfortunately it developed a leak. I was frustrated of course and reached out to the company as I was told it had a warranty, I provided a copy of my receipt and a picture of the damaged product. I received a replacement within 30 days! Thank you Clix!
