I have used this several times this summer. During a three day float down the John Day river and a fishing/camping trip on the Crooked River here in Oregon. Other people who had other good coolers were having to get ice daily in the hot 100+ degree weather, I did not have to replace the ice at all. The whole trip. I especially like the fact I can get into the cooler from the top as the clasps are located very conveniently there. Its amazing.
I plan on getting another one for sure.
Its a little heavy, but expected for the quality. I would also look at getting the wheel cart attachment.
