Sometimes (alright, often), really cheap versions of products that normally cost a lot of money are generally pretty rubbish. Cheap boots wear through. Cheap clothes don't fit well. Cheap fitness trackers are often poorly made, don't last long, aren't very accurate when counting steps or heart rate, and don't adequately protect your data.

However, we said often, not always. Amazon Big Deal Days, or Prime Day as it's more widely known, is the perfect time to score a great fitness tracker for a lot less than the RRP. For example, the slim Samsung Galaxy Fit 3 was $69.99 and is now $52.39 at Amazon and uses the same software as Samsung's more expensive watches, while the five-star, extensively-tested Amazfit Active 2 has been discounted from $99.99 to $80.74 at Amazon.

All the trackers I'm recommending here have been personally tested by me or a writer at TechRadar, and are discounted to under $100. Any one of these would be an ideal present for someone interested in getting active, or a gift to yourself to jump-start a new fitness regime. If you want to see more deals, you can always head on over to the Amazon Prime Day hub for more deals on everything from iPhones to air fryers.

Despite the name, not affiliated with Amazon: the Amazfit Active 2 earned five stars in our review, with our writer praising it as an unbelievable value for the price. Now it's down from $100 to just over $80, and that value prospect just got even better. It works with all phones via the Zepp app, is attractive enough with its metal body, and packs loads of accurate health metrics.

The watch packs a 14-day battery life, GPS, free offline maps, and 5ATM water resistance. It's quite large, with a 1.97-inch AMOLED display, so bear that in mind if you have smaller wrists.

It's a powerful, slender cross between a smartwatch and a band-style fitness tracker, although it doesn't have anything like the feature set of an Apple Watch at this price.

The fitness trackers listed here, whether slim bands or wide smartwatches, have all been tested by us.

If I had to choose one, I'd pick the Amazfit Active 2 as the best overall, but if you want a slim band, the Fitbit Inspire 3 is the best choice. If you can stretch your budget a little higher, you should check out our best Fitbit guide for info on the Luxe, Charge 6, and smartwatches in the range.
