Excellent product, i needed to straighten a 25 foot tall pencil thin juniper ,that had moved about 15 degrees from vertical during recent gales. By attaching one of the straps to the base of a concrete post, wrapping it around the trunk about 2 feet from the ground and gradually ratcheting up the tension over a few days i was able to pull the tree about 5 degrees in the opposite direction. When i released the straps all was well. I had to contact the company with a query initially, this was answered really promptly and solved straight away. Great service given the current climate.
