Super, easy to use, effective, comfortable, awesome! Used it and my Yeti Hopper on a 3 day camping trip this past weekend...while the Icemule doesn&#x27;t keep ice quite as efficiently as the Hopper, the Icemule is much more convenient and user friendly...i am looking forward to using my Icemule frequently, often, and long term! Even though the Icemule didnt keep ice quite up to the Hopper&#x27;s level, the over all package is great! I can say in most situations that call for only one cooler, I will saddle up the ol&#x27; mule...Icemule that is...hee haw...Thanks for a great product!
