Mark Healey raves about the Neuton CE 5.2 over on his blog. Here are some of the highlights:

Usually reviews are supposed to include pros and cons, but I can flatly state this mower has none of the latter....

The battery life, which I was originally concerned about, turned out to be more than sufficient. In fact, we found we could do two mowings on a single charge....

In my eyes, the Neuton has already paid for itself in just one summer.
