I am a professional auto tech. of over 40 years. I have had this for about a month or so now , it gets used on a regular basis by myself and the other techs in the shop.None of us have had any of the leaking problems others have wrote about. Maybe I got lucky. The only problem I have had is the legon is not accurate with the adapters for the different applications ,but if you pay attention there is one in the kit that fits .Another plus is the adapters are made of plastic , so they won’t corrode like aluminum adapters I have seen in the past. Those more expensive kits from the tool trucks have nothing on this kit, nothing . I am totally happy with this purchase.
