I tried one that a customer of mine had bought - not great; they have fairly hefty jaws and so are difficult to manoever and fit between congested limbs (which is why you might need them!). They are OK power-wise if you have a clear run of open-spaced limbs up to 1½" diameter - say, maybe reducing a laurel hedge by a couple of feet - a proper boys-toy! Buy a (Stihl) pruning saw and a pair of loppers - much more versatile! Good luck
