The Qalo SL-1 is a screenless fitness band from a company better known for silicone rings, and it takes aim at Whoop. It tracks sleep, heart rate, heart rate variability, blood oxygen, stress, skin temperature and menstrual cycles with no subscription, and it shares one health profile with Qalo’s SR-2 smart ring so you can switch between them. Each costs $200.
The verdict was lukewarm. The reviewer said a cheaper SL-1 would be an easy pick as a starter Whoop, but at this price there are better options, even after counting subscription fees.
The Una watch got a much warmer welcome. It is a basic GPS sports watch, but the owner can replace the back cover, display and battery with the included Torx screwdriver. The reviewer praised it as affordable, modular and comically easy to repair, and said it made the giants of wearables look bad.
Other testers agree on the repair side. Replacement parts in the US cost $40 for a battery and $50 for a display. In the UK, the watch sells for £179, with a display at £30 and a battery at £20. Battery life is rated at seven to 10 days. The trade-offs: there is no sleep tracking, the screen is a dated memory-in-pixel type that is best in sunlight, and it is only splash resistant, so no swimming.
