Taidda Digital Pitch Gauge, Mini RC Accessory LCD Display Lightweight Electronic Digital Pitch Gauge for RC Helicopter Model

I wish that I could tell you whether this thing works or not. But I rec'd it minus any battery. And its not an everyday batter; its a 2032 lithium coin type battery. I live 15 miles outside of town. Its not a convenient trip to the store to buy one. Its two gallons of gas and in CA that's about$10.50 worth. It would be nice if they specified that. I would have bought another brand if I had known. I paid a little more for this one thinking it might be higher quality and inclusive of everything needed. Nope. Will not buy this brand again.

I would have been nice if there were batteries!

Fast delivery but now I need to order the batteries! Packaging was open when delivered and the box looks taped over. But in reading other reviews, the batteries did not escape - they were not present. Please UPDATE your ADVERTISEMENT to say BATTERIES NOT INCLUDED! At $0.50/battery, I would have PAID the extra $1 to avoid this runaround.Update: I'm returning this unit. After trying to use it I found a couple of annoying problems. The first is that the auto-shut-off is timer based and not a timer after last use case and it keeps shutting the unit off before I'm ready. The second was exposed by the first issue and that is when it starts, it has its own idea where zero should be and you must press the reset button. But that is not enough, it resets to a value closer to zero, but not zero and you must press the "zero" button again to get to zero. Too much trouble when you are trying to get something done.

Great value for money, sensitive sensor really helps get an accurate read.

Does not come with batteries, requires 2 CR2032. Seriously?!! No clue how well it works because I don't have any batteries to try it out.

does not come with a battery!
