Someone in my friend circle has used the Aircast knee cryo cuff motorized version and found it really good.
I needed something which was more portable (as i travel a lot) but does the same work in reducing pain and inflammation.
I searched the web and found this product apt. The self contained cryo cuff does not need any cooler but has an inbuilt mechanism
where the cuff can be directly filled with water and ice and one can create compression needed with the hand bulb that comes with it.
It is almost similar to the cooler version except for the fact that the water in this one remains cold for a smaller period.
Nevertheless, if you are looking for compact and portable device that does the same work,
then go for this one.
