The chronograph is easy to setup and easy to get readings for most calibers and velocities. It seems to be very accurate. It truly is a great product.

The reason I don’t give it 5 stars is because it is incomplete and the app is way under developed. Generally folks have to buy a mount, battery pack, 90 deg cord, SD card, trigger device, a case, and a sight to feel like they are complete. I guess I would like to see the battery included or maybe internal and some discounted kits so it is clearer that a person needs about an extra $100 to get up and running.

The app drops connection, has no reporting functions, etc.....it adds nothing but frustration to the device.

The labradar works beautifully. The app is junk. I have a Samsung note 10 & it would not connect. Contacted labradar, not the friendliest people, and they said it has to do with the low power Bluetooth mode Samsung uses. Fix, reset network settings and reestablish all connections. Still didn't work, until I tried reinstalling the app. Now it works. Three stars, because that is ridiculous.

The functionality and accuracy of the Labradar is great. My only negative is that the iphone app software is woefully ancient. There is no way to label different strings and/or make notes other than on your own paper and hope you don't lose it. My $100 Chrony had far superior software. Having more functional software should be easy. Come on Labradar and get up to speed. Better iphone software raises my rating to 4.5.

I purchased it about 2 months ago and have taken it to the range 5 times now. It works great. The screen is easily viewed from my shooting position, so I can glance up and see the muzzle velocity of the last round. What I find the most helpful is being able to export all the data in an excel file. Then I can segregate different loads by powder charge and calculate the mean muzzle velocity, SD and ES for each group. Having used it for a couple of months, I think it was a bargain. If you're serious about your handloads this is a must have!

Pleased with the shipping time and the products performance so far, however, have not used it a whole lot YET...
