The second one was kindly offered to me last summer by Fiskars to try out. They have a gizmo on the downspout to divert over flow to the ground and has a cooler shape than the blue one. I tried two of them and unfortunately they both cracked and drained all the water collected. Fiskers readily replaced them. The third try Fiskars gave me a newly designed one. I am happy to report that it is holding water perfectly so far.
So, in summary I have to give a thumbs up to my water barrels as a necessary part of this garden landscape. A bonus is nice soft rain water and not hard clorined town water for my babies. Happy Gardening. Valerie
