I bought one to throw in my toolbox. I couldn't resist for the price.
The tip is fairly fragile (i.e. I've chipped mine already). It's
suitable for quick repeair on through hole sized parts, but too big for
surface mount stuff.
There's no way I would use instead of my regular iron, but for an
emergency repair, it fits the bill.
