Popped a couple caps on a qfp proto board and started a reflow cycle. Dry run went OK. Unit was dropped pretty bad. Frame is out of whack and drawer bent. Seems to still work. Not sure if damage is shipping or existing as I didnt have time to test and inspect in the market. Shame on me. Still seems to work. Much like the t9xx units the timer does seem to be a little slow compared to a stopwatch.
