Koolpak Instant Heat Pack - Soothing Pain Relief for Neck, Back, Shoulder & Arthritis - Portable Single-Use Hot Packs Stay Warm 40 Mins | Compact Size 15x23cm for First Aid, Travel, Camping (20 Pack)

Used these a few weeks ago on my sore knee. Worked great.

So many in the delivery... too heavy to carry of fit in one tote. Suggestvsell in packs of 3 orc5 or 7, maybe

amazing

Does the job but the heat won't last more than 10min.

Great product they dont stay warm for long thats the only down side to them and the fact that they can be hard to pop to start them heating up but very good amount and good price as well

Pretty good but heat only last for a few minutes

This was the cheapest place to buy them. Really handy to keep in the car and for travel- stays warm for about 5 mins

It failed to meet expectations as a arthritic working person ache and pains are a fact of life but this was by far the saddest excuse of a heat pack Iv ever used it doesn’t get much hotter then a phone on a hot day and certainly not hot enough to do in deep muscle relief not only that but it lost that little bit of heat not even 10 minutes later the instructions where not very clear at all and to top it all of I can’t even send it back or get a refund overall will never use this again
