Ballistic Precision Chronograph 30-9999 FPS Speed Meter Large Effective Area Meter Used for Tennis Badminton Shooting Chronograph Shooting fps

I bought this last year and finally have a chance to use it since the weather is gotten better when it arrived one of the buttons was gone, which was no big deal I fixed it put it together to use it and it’s a piece of junk it does not work cheaply put together I’m embarrassed to say I even bought it

It does what it is meant to do, accurately read the speed of something....👽

I've used this chronograph a few times now, and although it seems to be working so far, the buyer should be made aware that the unit feels really flimsy and cheaply made. As far as the directions go, to say they are imperfectly translated from Chinese to English would be like saying won ton soup isn't quite a chili dog. The instructions LITERALLY have nothing to do with the product! It's as though the manufacturer put the directions for a completely different electronic device into the box. Not a single thing can be gleaned from the instructions regarding set up or operation of the unit. As examples, there is nothing stated about required batteries or how to insert them, how to attach the screens, how to change the reading from meters per second to feet per second (or even that such a feature exists - thanks Youtube), or what distances are optimal for proper calculation. The directions don't even say how to turn on the device. I'm not going to return the unit, because it does appear to be working as advertised. I am, however, probably going to buy a better chronograph on Amazon and keep this one as a reserve. Just a little caveat for the emptor...

Instructions for use impossible to read, translation from chinese to english couldnt be deciphered and it was a printer paper.Packaging was insufficient to protect the components. Screws and parts were all over the place and bent.Producer of this product is incredibly incompentent, pay a little more for a real device from a different vendor.

Junk don't buy. Opened package and a wad of solder fell out of the box. I'm returning Tuesday after Labor day

Bad reading

this product is the worst item I have ever got from Amazon it doesn't work at all

bon produis
