Pro-Tip: When using high-BTU heaters like the Tradesman 400, tank sizing is critical. A standard 100 lb cylinder may freeze up due to the rapid rate of vaporization required by a 400,000 BTU draw. For uninterrupted performance, always use a minimum 500 lb tank or manifold at least two 100 lb cylinders together.

Actually works on BMW!
I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
