I have also given them away.  I always keep one handy though
for rough field work, wood shop, etc.  They're marginal quality.
But any DVM is better than no DVM.  If lost... well, no big deal.

One thing to keep in mind.  I have a Harbor Freight DVM; it
wasn't reading the same voltage as my Fluke -- about 10% off.
In my unit, I found the problem was the weakening 9V battery.
Raw battery output voltage appears to be the reference voltage.
A new 9V battery brought DVM back into reasonable accuracy.
