Battery charging is quick, but the battery charge is sufficient for only about 10 to 20 minutes to mow (depending on grass length etc.). So necessarily get 2nd battery or buy the more powerful version.
The mowing result is impressive, as is the collecting of grass is fine. The mower is extremely handy and easy. Unfortunately not suitable for my purposes, because I have a 1000 square meter plot of land and wanted to mow with this mower only the edges under the bushes, but there is not enough battery life.
All in all I would have to live with the mowers and had me worried a second battery (which are not cheap!). Unfortunately, the mower was now no longer start, so Amazon has taken him back.
My conclusion: ideal for mini-lawns, otherwise look for an alternative.
