This was a GREAT purchase!  I almost went cheap and thought about buying a Harbor Freight cut off saw, but I looked at a few reviews and realized my time is worth more than it takes to buy and return a bad tool.  So, spending 3 times as much, I went for the Makita.  So, cudos to Amazon, it arrived in two days in perfect condition.  Unboxing, found it drop dead simple to use.  Went to work today making 25 cuts in cold rolled steel channel material to build a brew stand for my son-in-law.  Based on the reviews I went very slow for the first dozen cuts, then started to push a bit harder.  Much to my surprise the cutting started to go much, much faster.  There was more burring of material, but for the dramatic increase in speed it was well worth it.  When done, I had only used an inch or so of blade material.  All the cuts were perfect, 90 degrees.  Oh, I had it plugged into a powerstrip that measured AMPs and when pushing hard we were bouncing between 16 and 20 amps, so if you are running on a 15amp service you may need to go easy.  All in All a GREAT purchase.  I'm sure this tool will give me decades of great service.
