    • Real-Time, Real Awesome!
Size: 1-Month
Small and lightweight. The sensor is located in the HPM and goes onto any bat pretty easily. We're using a B45 wood bat and a Marucci Cat X. It's cool because it supports multiple players and bats. App was simple to setup and we were hitting dingers in the Home Run Derby game in no time! Looks like it only took 100 swings to achieve our "Swing Score" which is made up of a bunch of key metrics. It's cool because it gives you recos on what to work on. From a performance, data accuracy and collection perspective– it's legit!! Not sure on the battery life just yet as I haven't had to recharge it yet. Seems pretty good so far. The challenges are fun and the lessons go deep – especially the ones with MLB players. They also have a bunch of games you can play and the couple of digital rewards/badges we got were fun. Added bonus, they give you MLB highlights where you can guess the players. Pretty cool! ... show more

Review Image by SETexan
I hate giving bad reviews on smaller startup Companies, but this product is pretty cheap and unreliable. It’s the end of baseball season for my son who is in 12U travel baseball when I found this product. The reviews seemed decent and the five star rating on Amazon wasn’t too bad, so for $50 I said hey it’s worth a shot. It arrived pretty quickly. Charged the sensor for 4 hours. Then paired the device to my phone. It immediately request a firmware update. After the update completed, the sensor rebooted and the app kept telling me to toggle Bluetooth On/Off. I did and the app was kinda hung in this state. I killed the app, restarted and reconnected to the sensor. The app would re-pair to the sensor as long as it was on the charger base, but it would not wake up when removed from the charger base. After missing practice the window and fighting this for 24 hours, trying to find answers online, I requested a refund. I would rather pay more money for a better made product. ... show more

    • Love this product. Wanted to give a 5. Read.
Size: Bat Sensor
I absolutely love this product and wanted to give it a 5 start review. However there have been issues. My father and I run a baseball/softball school and we have around 100-120 kids that come through our facility weekly. We use this product along with other products to test, track, and set goals for our athletes. This product is great for tracking launch quickness, bat speed, hand speed, time in the zone, barrel path, and some other awesome metrics. It’s also easy to use with several players and can be switched from 1 player to another quickly for team use. The 3d visual of the barrel/bat path is an excellent resource as well. However, I had to return the first sensor I bought because it became stuck in the casing that attaches to the knob of the bat. Amazon refunded me no questions. This second one does not turn on all the time. We have constant issues with getting the sensor to turn on and every now and then the sensor misreads a swing, which is no big deal, but the 3 star rating is because we have issues getting the sensor to turn on. I do need to call diamond kinetics. I’m sure they wjll rectify the problem. Bottom line, great product I highly recommend for kids of all ages (10+). ... show more

    • Don’t Second Guess This
Size: Bat Sensor
Get the 1 year version. I started with 3 month to try it out but it’s so sweet, save real money and go with the year. I don’t use the games or goals, only the bat tracking and that gives me every reading possible for softball and can imagine the same for baseball. I rarely rate anything a 5 which to me is exceptional. The support for setting this up and questions is done through the app and the best there is. I lost my sensor and they sent me a new one in two days no charge. I recommend that you study the metrics on their web page for what applies to you the go out and bang the snot out of this thing with your bat! ... show more

    • Only held for one charge
Size: Bat Sensor
It worked great but wouldn't charge after original charge. Customer service had me take pictures while charging, not sure what they wanted to verify but Amazon was quick to send replacement. Will try this next one and see how long it lasts.

    • Zero Stars
Size: Bat Sensor
Zero stars if I could - My first clue that the device was going to be a POS was when it had issue charging when I first received it. Now attempting to connect to Bluetooth and the app has been a nightmare. It won’t connect but in the off chance it does it will immediately disconnect. Most of the time the app doesn’t respond to simple commands, UI is awful and doesn’t do what it is advertised to do. Returning the device and deleting the app. ... show more
