Thing extends extremely high and is great quality for the low price! Very happy with it. I recommend it frequently to friend and family who need to prune larger trees on their property.
I really like this product. I have been able to reach branches and limbs that are too high to climb up to. You have to be strong to use it with ALL of the poles connected. There is one flaw though. There are metal pins sticking through the poles to hold the connecting attachments. These have worked their way out and I cut my hand on one. Hammering it back into the pole and flaring out the ends have secured the pins so far. They should be rivets and not just pins. The blade that cuts the branches has been amazing. It is so sharp green limbs are a piece of cake to cut.
At full length, this is extremely heavy to bring up to the tree the first time from the ground. I prefer this pole because the attachment points are much stronger than the screw on type and they don't unscrew when you're working with the saw. The sawblade design is excellent and much easier to use than standard blades. The carry bag is very convenient for storage. So far so good but if you twisted or get it stuck in the tree, you could break the saw attachment point so be gentle.
