Fortunately the weather has been great for the middle of February or all I'd be writing about it is that it looks durable and should work well in my pond. I ordered this so I'd have a backup for when my current pump dies. They normally last me three to four years on the current model I've been using and this one looks sturdier that what I have been using.I ordered the 3100 GPH version as that's the same size as I've used in the past. I run the pump all wnter long keeping the water moving and not allowing the pond to freeze totally over. I pulled out my current pump and replaced it with the Vevor and I'm getting the same throughput, as I expected.I chose this pump because it was the same brand as a sump pump I had ordered earlier and was impressed with the quality. I feel the same about this one. I fully expect it will be a strong and long lasting as the one I'm retiring as a backup.
