Corner Boxing Smart Punch Trackers - Measure Accurate Punch Count, Speed & Power Performance in Real Time – Stay Motivated at Home & in the Gym - Bluetooth Compatible with iOS & Android

I live in the U.S. and couldn't find anything like these here, so when I was last in the UK, I bought them. They work really well and you can use them as trackers with or without the app's workouts (there is a Quick Start/Manual option and you can use these in your own gym or workout--haven't tried that yet, but will when my boxing class isn't impacted by Covid any longer). Anyway, I'm currently using these in my home with the app workouts. I love Paulina's workouts--they are hard but you feel like you've really done something afterward. I have yet to try to the other coaches. I'm sure they are also good. The trackers not only track the number of punches but power and speed too. It tracks your averages, it compares those stats between your left and right hands (uppercuts, jabs, cross, hooks, etc.). They are so worth the cost. I've interacted with customer service a few times about the app (there was some promotional thing going on) and they honestly have the best customer service. I'm finally getting back into shape after months of Covid stasis. Thank you CORNER!

Excellent, and exactly what I wanted. Ideal for anyone curious about their performance on the bag

Like some of the other reviewers, I was worried by some of the reviews posted, but nevertheless decided that I would give them a go, as they seemed to carry great promise. I have a busy schedule and my gym workout times are fairly inflexible. I spent over 2 hours during the weekend trying to get the sensors to connect and eventually gave it up. I don't stand in front of a punchbag in my gym, spending half of the time I have to workout 'double tapping' sensors to connect. Completely useless and, in my opinion rubbish. I am angry and frustrated that I even wasted my time with them. They arrived Friday - yet there was no customer service over the weekend, which I thought appalling and even more annoying. They are boxed and awaiting pickup to be returned.

I’ve had these for a couple of months now. At first they were a bit frustrating to get to pair properly but after updating my iPad and the corner app and firmware it pairs first time now every time.I use them alongside boxing training videos on a heavy bag. The trackers are really good for adding motivation to push yourself and to try and improve your previous personal bests.Hopefully there’s much more to come as the app itself and the data is pretty basic but I’d expect this be developed over time.As they aren’t that expensive, I think they are good value for helping motivate you to push harder in training sessions.

A simple idea well executed...

I would give a four out of five stars for the trackers! They can be a bit temperamental here and there, but once working, they're absolutely brilliant to train with. From what I can tell, they are very accurate on a punching bag. I tried it for a boxing PT session I had and they seemed to pick everything up fine. One of the trackers did stop working. These were bought for me as a birthday gift so I didn't have the receipt but luckily I kept the box which had the serial number on it. I decided to email Corner to see if they could help me. Well, I was blown away from the customer service. The person who responded was great and asked for some form of proof of purchase which is completely fair and once confirmed, they were happy to help me. They arranged for the tracker to be sent back and tested and also organised so that I could order a replacement for free. They responded to all of my emails and queries throughout the process. I now have a replaced tracker and all seems to be working perfectly! The extra star is for the exceptional customer service which is why I have given this five stars overall! Thank you again Corner, I am happy to be back training with them!

The gadget is a good idea but unfortunately it missed most of the punches and kept losing connection

Surprisingly small size devices. Tested for about 15min boxing and I am very satisfied of the accuracy of detection. It didn’t miss any of my punches.
