Very true if you don't have a good ground and have an ark from where your welding ground is mated to the frame you also can fry your computor.

Same with boat motors!

I always disconnect both cables from the battery just to be safe.

Anybody ever use these? Several different ones and prices.

Never even seen one before. OTC is a pretty rep company, but my problem is you can just disconnect the batt for free.

On a modern car with tons of modules that sometimes need to be "reinitialized" after a battery disconnect, i can see it being more useful...but then again, you can just use a memory saver device for about the same money and (to me) less risk. To me, its kinda hard to justify.

We use them where I work building custom work modules on base chassis. No issues I know of.

Actually, you should always disconnect the negative cable first. It is the only cable that needs to be disconnected.

Pulling both is fine. But still be sure to remove the negative first. No sparks or shorts if your wrench also touches metal while touching the negative post.

I am a weldor and am cross-trained as an electrician.

I think this thing is cool (if it works). I will probably only weld on my SxS 5-6 times in it's life. Not worth it for those few times.
If a mechanic could use that instead of disconnecting the battery it would
