The Pocket Pinger + Stack Stick, Coin Ping Test (Black, 1 Pack) + StackerTools App

I bought this because the concept appealed to my nerdiness. The app works great, but I'm excited for the Android version so I can use it with my personal cell. The current "coin library" is already pretty extensive, and from what I understand, they continue to expand it. My only regret is that I do not have a fake coin to use as a negative control! Farshod seems like a good guy, provides lots of guides on how to use the tool with various coins.

I love this thing. Plus with the app, absolutely amazing. The fact the founder (Farshod) gives out the updated app (premium version) @ $0 cost to all prior purchases is insane! Genuine asset to the community & great company to support. Get one!

Easy to use

As described and easy to use. It is much easier than balancing on a finger tip, and produces better results. But the gadget is not a spring hinge -- it is a single piece of moulded plastic that you must bend. Hope it does not snap at bend point. Must be used in conjunction with other tools (calipers, scale, N52 handheld magnet or magnetic slide) - it will help identify fakes. I think it is very pricey.

When i was looking at the review’s before buying this i was not 100% sure i did ask the person how makes them and i did order it very happy so far and i did get the full app no problem and some question's the person making them always was the replay with an email very help full wil for sure recommend it

This thing is great for identifying fake coins.

Highly recommended having one of these if you’re gonna collect any types of coins. The accuracy is just about perfect especially if pair with the app. Definitely recommend. Fast and easy shipping and showed up a couple days earlier than expected. Great service. Highly recommended and very affordable and very useful.

The perfect tool to confirm your coins are good or not. Every single time you get a good ring! This is a must have!!
