Bit disappointed with the lawnmower on first use, both batteries fully charged so tried cutting the front lawn (a fairly small area) and the first battery lasted all of 10-15 minutes, definitely required the second battery and this one just lasted long enough. Yes the grass was longer than normal however I expected a bit better than this given the price of the product. The strimmer is great despite the large amount of vibration it gives off, the battery seemed to last for ages when used with this. Overall, decent enough products but the battery life is really questionable for the lawnmower - I thought based on a lot of the positive reviews of this lawnmower that it may be better.
