I bought this to tackle a very overgrown patch in my garden. In three sessions I managed to get the shrubs under control and shaping the bushes was made easier because the trimmer isn't too heavy. I only got a "jam" twice and on neither occasion could I blame the machine, as large branches were the cause. Charging the NiCad battery doesn't take too long. On my experience you only get about 30-40 minutes of cutting time per charge, so it's fine for light or occasional use. For more extended jobs, you could buy an extra battery, so you can charge one as you work with another in the trimmer. A good piece of kit - I'm glad I invested in it.
