### ⭐⭐⭐⭐⭐ Great quality.

Fits the mz3 and is still going strong after months of daily use. It's definitely worth getting a second strap so you can wash them more frequently. These get popped in the washer and hung out to air dry.

### ⭐⭐⭐⭐⭐ Excellent replacement
*by J***N on 20 May 2025*

### ⭐⭐⭐⭐⭐ Same as original
*by S***H on 4 November 2025*

Great replacement strap, I actually ordered the small as my original strap had stretched and was losing contact, as well as starting to smell on the rubber contacts - I tried everything to get the smell out, washing, anti-bacs, even after bleach, bicarb & vinegar could still smell it so had to buy a replacement, and very happy with this one. After adjusting it fits perfectly, rubber contacts good and presstuds are in the correct place so the monitor clicks in firmly. Please note, this is for the original oval shape monitor not the new smaller, round one.
