Safety First Aid GroupHypaGel Reusable Large Hot/Cold Gel Therapy Pack for Sports First Aid, Muscle and Pain Relief, Single 30cm x 20cm - Microwave and Freezer-safe

These seemed such good value for money, I bought 2 in total (so 4 packs)They are an excellent size, I have been using them on one of my ankles that flared up after some cross country running, they get cold extremely quick and the effects last a long time.I have not used them for heat, but you don't put them directly in a microwave, you heat them in hot water inside the microwave.Something everyone should have in the home!

After my old ice pack started leaking I found these and they are perfect. I love that it’s a set of two so can use one while the other is chilling and then change them up. I haven’t used them for heat yet so can’t comment on that. But when frozen they are perfect. I injured my knee and this has really helped. They are a good size and are really good quality so I can’t see them leaking anytime soon.

Quite a multi use ice pack. So not only is it a standard ice pack, you can also heat it up to use a warm pack.As an ice pack it is fairly standard. Straight out of the freezer it is still pretty maluble and forms to the limb it is applied too. It certainly does the job. If you have kids it just makes sense to keep on in the freezer all the time for any potential accidents.When using it as a warm one it is fairly effective. It doesn't retain its heat for much longer than ten minutes however it does work well.The plastic wrapping feels very strong and robust. I have plenty of faith that it could handle a fair bit of pressure.These items are a must for any parent.

Really useful, quite big! Bought one for fridge, one for freezer as I have little ones who often have bumps. Haven't needed the freezer one yet but the fridge one has been really handy. Most importantly, I'm sure someone put there must have issues with itchy eyes that swell like me. I had no idea how amazing this would be for that too!!! Would recommend, or a slightly smaller version if they sell one.

As an ice pack this does the job. However I used one as heat pack and on the third time of heating in microwave (three separate days for no more than 60sec) the plastic covers had small burnt holes in with the gel able to seep out. (see attached) Unfortunately this effects using it as a ice pack now as it freezes rock solid due to air getting inside.On the instructions it says to microwave in water, but no where in the 'CAUTION' section did it say there was an issue with just putting it in the microwave outside of water. With other heat packs I've always simply put it in the microwave for a quick blast and had no issues.
