I read the reviews and thought it was this or a smaller Bosch Rotak. I thought the extra width would be better. Last couple of weeks it's been sunny, so waited till it was a nice day. The lawnmower is easy to setup and the battery was showing as charged even though I have not touched it since early December. The mower itself is reasonable in weight, considering it is the large, would be equivalent to the weight of a cheap and cheerful low-end petrol mower. Started up straight away. Which is a bonus as I am used to using petrol mowers. My last petrol mower was a beast in weight, however the rear plastic wheels broke/cracked after a month. So, thought I'd try a cordless mower. My lawn is reasonably sized 13m x 10m and a few odd bits, which are of little significance. The grass was pretty long in certain areas, put the mower to setting 3 and walked the walk. I managed to mow the whole lawn on the charged battery, I guess I could have done another 2m x 2m by the time the battery may have discharged completely. I was pleasantly surprised as I thought I'd only get a quarter done. It comes with two batteries and I have a third from my Strimmer. The nice thing is the LI-ON batteries can be used within the Black & Decker range. The nice thing is the mower had no issue cutting the really long grass if anything, my petrol mower would have stalled on it. You can hear the motor power working harder on the longer grass, so the motor is providing the extra power when needed. I was skeptical as one review and comments suggested it was poor quality. However, this mower has stood up well. It is powerful and the battery lasted. It is a big mower and I wouldn't expect my mother to operate it. But, it is manoeuvrable and easy to handle from my perspective. As it is big and powerful, it made light work of the lawn. I guess if you had a lawn over double my size, then of course you'll need 2-3 batteries. Now, I can't say if the LI-ON batteries are at fault as I have had issues with earlier LI-ON batteries on a different B&D product. However, the two that came with the mower seem good, considering the length of the grass it tackled. Final thoughts, I definitely give this mower a thumbs up. It is big and powerful, the Autosense kicks in and works a treat. The batteries charge up quickly as well, fully charged in less than 30 minutes. So, cannot complain really. Overall, very pleased and happy with the Black & Decker CLMA4820L2-GB Cordless. Review: You'll need both batteries for a good sized lawn - Heavier than looks and is underpowered.
