MYZONE MZ-Switch Physical Activity Heart Rate Monitor – A Water Proof Fitness Tracker For Wrists, Arms & Chest

Does exactly as described. I like the alternate options on where I can wear it depending on my activity. Chest strap definitely more accurate but the versatility is unmatched.

Love it. Blaze classes at David Lloyd wouldn’t be complete without it! Battery lasts me months at a time.

Works as expected

Works very well, use it on my wrist and it gives continuous and accurate heart rate and effort % readings, the only thing I am dubious about are the calorie readings which are obviously wildly inaccurate, apparently I expended over a 1063 calories on a 1 hour 17 minute brisk walk, I don't think so, otherwise very happy with it.

Superb fitness tracker great battery life great app

Be ready to be disappointed.bought the device for £139 and an extra wrist straps at £4.99.on the 22nd of August 2025, the charge runs out quick and the device does not perform well

This device is the upgraded version from what I had. It provides wrist and arm strap for more convenience. Wrist is used for non gripping activities only unless it isn’t accurate. We can use it for swimming.

Excellent
