This is the best. Do have one of my gel packs that doesn't freeze as well as the other three but this is so helpful after having two knee surgeries.
Needed to be able to have a rotating number of packs so purchasing another pack helped the process very much.
I have use these eyedrops for the past three months. They have been an excellent help to reduce my swelling from my August 24 Knee Replacment.
I was expecting the one with the little packs inside like the ones the hospital gave me.
Fantastic for knee surgery recovery.
