My new toy, i love it, my Brother has 1 of these & he showed me how it works a year ago, i've wanted 1 since then but wasn't that keen on the price, (even though it's worth every penny).
I eventually bought it when it was on sale & i'm a happy bunny now.
I had some surplus plum trees to get rid of & lots of other fruit trees that need cutting back on a regular basis, this tool is just perfect for the job, (it's quite heavy so i can build up my muscles in the process of getting the work done ha ha).
I didn't want to get a chainsaw but knew that i'd need something in that line, this has a brilliant safety feature in that you have to hold both grips to make it work, so it's impossible to cut your hand off unless you have 3 hands.
You need to oil it after every 10 minutes of regular use (not a problem, it's easy to do & takes about 2 seconds) & they recommend that you buy their oil (they do supply about half of a small bottle, which is plenty to get started) i asked my Brother if i could get away with using just any standard 3-1 type oil & he said yes, in fact he said "any engine type oil will do, if it's good enough to run a car, it's good enough for this".
I can fully recommend this product.
