i love my stroboflip, although some people struggle to use it at first.
No problems with mine, once you get used to the sensitivity it's a breeze. Also, I've noticed how much better dual lead tracks ala Thin Lizzy sound since in I've been tuning my bandmates guitar too!
you wouldn't use the meat knife on crusty bread but, equally, the serrated knife and straight edge knife aren't going to go through raw meat as quickly
