This arrived requiring about five minutes to unpack and assemble. Assembly was straightforward and trouble free.
Once assembled, operation is also straightforward. The telescopic element is easy to operate and lock into place. I managed to "over lock" it once, and struggled to release the lock again afterwards, especially with tired arms, so learn from my mistake!
The weight of the motor etc is firmly towards the end of the pole, which means that at full extension it is quite hard work to hold and you will end up with tired arms - unless you are considerably stronger than me.
A 400 watt motor may not sound like much, and the maximum branch thickness is not huge, however the cutting blades are sharp and work well, and the cutter made short work of the difficult to reach bits of hedging for which it was purchased.
