How accurate are smart jump rope calorie counters?

The best models are within 5-10% of heart-rate-validated burns. LED and Bluetooth-connected ropes tend to be more accurate than standalone LCD counters because they can factor in your profile data.

Can I use a smart jump rope on any surface?

Yes, but we recommend rubber mats or gym flooring. Concrete wears cables faster, and carpet can snag. Most manufacturers include surface recommendations in their guides.
