Atty's definitely last longer being in the liquid, there is no doubt about this in my mind, I here people always complaining they blew there LR Atty and it's simply because they dont keep them soaking wet, after using LR Atty's now for a few months or since they where introduced it is obvious to me that all Atty last longer keeping them wetter than ever, LR/Reg/HV/XHV all of them.!! So being submerced in the tank of liquid is great they should really last a long time in my opinion much longer than dripping or using carts, hahah did I say carts, thats an old old thing of the past isnt it now guys.!!
