The silicone band is comfortable and easy to adjust, and we were delighted to discover that unlike many kids’ watch straps the Fitbit’s band didn’t irritate our younger tester’s very sensitive skin. The strap fits wrists from 116mm to 168mm in circumference, and everything is water-resistant the Ace 3 is good to 50m so it can stay on in the shower or when your child is swimming. Other colored straps can be bought separately. It has an adjustable plastic clasp and currently comes in two options: dark blue with green clasp and black with a red clasp. The Ace 3 is more rounded than the Ace 2, and looks more modern as a result. Like its predecessor, the Fitbit Ace 3 is a small, rectangular pebble enclosed in a silicone band that protects it from lumps and bumps.

Update: In June 2021, Fitbit also released the Fitbit Ace 3 Special Edition: Minions, which has a Minions-themed engraved band and special activity badges. That's almost identical to the Garmin Vivofit Jr 3 kids' fitness tracker, which costs $79.99 / £79.99 (but is substantially more expensive in Australia at AU$159).

The Fitbit Ace 3 was released in March 2021, and costs $79.95 / £69.99 / AU$99.95, direct from Fitbit (though you may be able to find it more cheaply at third-party stores). The Ace 3 is good-looking, comfortable and tough enough to cope with even the most exciting adventures.

The Fitbit Ace 3 doesn’t come with lots of flashy features such as movie tie-ins or cartoon characters, and we think that’s a good thing it doesn’t look like a childish device and that proved to be a big plus for our testers.
