Been in the cable industry just over 5 years and have been using the same compression tool. I have abused and miss used this thing and it still works flawlessly. I ordered a second one so that I could have one in my belt pouch and one in my house pouch instead of forgetting which one I left it in and have to come back down the ladder, or back out of the house to get it. This new one just happened to be adjusted perfectly right out of the box for a full compression on rg 6 and 11 connectors. Very easy to adjust if it ever gets out of adjustment with a couple of allen wrenches.
