Seems to work well right out of the box. Price was right! Easy to insert the batteries (included). Great little pouch and nifty lanyard to hang around neck, if desired. Easy to read screen. I like that it shuts off automatically, so you don't have to remember to do so.
THERE WAS AN OFFER FOR A FREE 4 port Smart Phone Fast Charger, BUT THE LINK TO FIND THE ORDER NUMBER DOES NOT WORK, SO I AM NOT ABLE TO APPLY FOR THE OFFER... I AM DISAPPOINTED)-;
