Yeah... I'm not big on government restrictions. I don't think it'd be a good idea to mandate these on all table saws.My husband debated getting one for me. The video was hard to watch, even with just the hot dog. I seem to remember the unit cost for adding the technology was sizable enough to price lots of people out of the table saw market if it was mandated. I'll talk to DH and get the straight dope. He did some research on it.
The saw is not finished after the brake fires. The cartridge is replaceable though it does cost ~100 dollars and it takes the blade with it.I think it's a cool concept, but isin't the saw finished after it? I would prefer something where you can just reset it. I'm sure there are possibilities of false positives such as if the wood is wet.
I also wonder how well it works when a finger is going fast through it, say you're cutting thin pieces of wood and just passing them through real fast.
