I ran a hammerhead for 4 years. It was a horse! Had to dial it down. The issue with Reeflos are the seals. They do go from time to time.
I'm running a Snapper now, just like the hammerhead, quiet, lots of juice, low energy consumption. The seal has me nervous. Thinking of changing to a blueline. I've run them in the past. Not as eficient as Reeflos, but pretty darn good, and very quiet. Easy to work on too.
I've yet to replace a seal on a Reeflo, but I guess it's not that bad.
