gnappi,
The ones I show in the link are similar length as yours (6-10ft). Let us know what you think of your purchase once you use it to pick your lychee fruits.
I did a review on Ebay for it, here it is:
The best I've had yet (OK of only two) :-)
The 10' extendability is REALLY handy for those tall trees with fruit on top! Add a 6'-8' ladder and you'll be denuding your trees of fruit and pesky branches you've wanted to prune in no time.
Cut and hold on to the cut branch, or let it drop, your choice. One niggle... with the pole at its full extension you'll need a LOT of space to swing the pole in an arc to drop your fruit safely to the ground, but for trimming branches without fruit, I hold them just long enough to find an open spot for the limb to drop.
It's cutters are very sharp, and cutting limbs to just under 1/4" in thickness is easy, anything over that is a chore.
The LED flashlight for tree trimming and fruit collecting at night is worthless. Any cheap 18650 CREE headlamp will illuminate the canopy far better without shadows from the aluminum pole.
This one is well worth the price, I'm very happy I stumbled onto it.
Quote off.
