I purchased my Ultra Cool the end of January 2017. I installed it the first week in February. The install went well, although I recommend a lift if you have one available. I have been waiting to review the Ultra Cool until the Florida heat started to kick-in. The unit is on my ’04 Ultra Classic- and the old glide really likes it! I was caught in a traffic jam on a very warm Spring day. Normally the bike starts running rough standing still in traffic. Well, Ultra Cool fans kicked on and kept my bike running smooth as can be. I checked around before buying the Ultra Cool. It honestly performs as claimed. I feel it offers the best bang for the buck. SO, if you are considering a great system to cool your bike, you found it with Ultra Cool! Thanks Earl for your tech tip!!
