Not a perfect monitor for every fitness… Not a perfect monitor for every fitness program - but overall it seems to work. Best if used as a reference level monitor - not actual count for calories burned. Just a good assessment if your workout effort is going up or down from day to day.

Replacement received very quickly Have just had my MZ-3 replaced (it developed a battery issue) with no quibble and no delay (5 day turn around). The customer support team (Melissa and Abigail) were helpful and responsive, and I can't fault their assistance. Thank you Myzone UK.

PRODUCT WONT HOLD CHARGE AND NO CUSTOMER SERVICE We wrote them on Feb 19th, finally got a response back from Abbie (weeks later) and she asked us to confirm shipping address but then never wrote back or sent the replacement. Then we wrote to myzone again and Gie responded, asking us to do all these tests. We completed the test and the item still doesn't hold a charge and now no response from Gie. I agree that they are trying not to cover replacements. DO NOT BUY THIS PRODUCT!!!! NO CUSTOMER SERVICE AT ALL. UPDATE: we responded to the email address that that myzone left in the response to our review. We sent a copy of all communication to them that we had with Abbie and Gie. They talked about what each individual should have done and how they plan to use this to train customer service. We received the replacement within days of writing the review. Appreciate the help in getting the replacement.

Updated review Update- I did finally get a response from Myzone. Credit where credit is due a MyZone manager took over my complaint and offered me an exchange for my faulty device. This was easy to do and was swapped over at my local David Lloyd gym. I’m sure the team are working hard to catch up with the back log of raised tickets and felt I needed to change my review. It took a while to get a response but my ticket was eventually sorted with the resolution I wanted. Hopefully myzone gets back to full service soon Original review Lost all faith. I used to rave about the customer service at My zone. Always found it very helpful with a speedy process. Not sure what has changed. I have sent multiple tickets for a faulty device not detecting my heart rate. To this date all tickets have been ignored. I appreciate there may be a delay in response time, but the website doesn’t show this. My first ticket was raised 4th March Not sure if there is a technical issue with the ticket system, but I am stuck with a faulty device and no way of communicating my problem. From 5 stars to 1 one star

Awful customer service.. Awful customer service... Happy to take your cash, but the after sales support is woeful. Currently waiting 7 days for a reply to my message - 3rd separate time I’ve been in touch to resolve the same issue. Shame, because the heart rate tracking is actually really helpful.
