The data for each shot can be played back in sync with the corresponding video which enables you to take a closer look at your shot data after each game. Through this function, you can easily spot the areas for improvement, just like having a trainer by your side at all time.If you have forgotten your smartphone, don’t worry.

After you finish playing, connect the sensor with your smartphone to import the data into the app. A play report will be automatically generated. Also, in Memory Mode, the battery of the Sensor will last longer compared to Live Mode since a smartphone is not connected.So grab your racquet and get cracking.

At least the one I received didn't work. It charged as it was supposed to and I could connect it to the app on my phone, but the sensor itself didn't turn on to record my swing data. The instructions say to shake the racket to turn it on, but that didn't work. I played for an hour with it on my racket on two occasions and it never turned on or recorded anything even though I had just charged it fully (read 100% charged in the app). Thankfully, Amazon has a generous return policy. ### ⭐ 1.0 out of 5 stars wouldn't recommend it. *by R***A on Reviewed in the United States on July 5, 2017* I bought this almost a month ago for my tennis practice. It was working almost fine for the first couple of sessions, but suddenly stopped working and battery never gets charged, no matter I leave it plugged in. The other negative point, training video recording feature never worked, even when the sensor was supposedly working. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars I ordered this product as a Christmas gift and she ... *by A***A on Reviewed in the United States on February 14, 2017* I ordered this product as a Christmas gift and she loves it! I am impressed with how much the product tracks! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/31054236-tennis-sensor-bluetooth-training-analyzer-track-and-record-performance-real](https://www.desertcart.be/products/31054236-tennis-sensor-bluetooth-training-analyzer-track-and-record-performance-real) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-06*
