I like the way the pieces go together. A good secure fit between the extensions. When using three extensions or less, it's manageable. More than that, it gets heavy. If you have multiple branches to cut from the same tree and you're using 4 or more extensions, cut the top one so the saw will only fall to the next branch instead of all the way to the ground. A few times lifting the saw blade up 20 ft is quite a workout! My saw came with a broken handle on the cutter string. I contacted Vevor customer service with a picture and proof of purchase. I got an immediate response telling me how they were going to rectify the issue, which was to get the part shipped to me. They warned it could take 3 to 5 days. Each day I got an email with a status report. After 5 days, they let me know the part was going to take longer than expected and rather than wait, they wanted to fix the issue by sending me a whole new unit...and I was able to keep the original!
