In addition, I use a Samsung watch 4, so I always have something to benchmark it against. The operation is straightforward, without any unnecessary extras, and it also has the capacity to take phone calls. The quality of the materials (glass, body) is satisfactory, and the measurements are rather accurate (the differences with Samsung are negligible). The battery life is approximately 5 days (containing everything, with no savings). I only used it for training purposes (the pricing turned out to be really good; after reductions, they cost 14,200). If it weren't for its enormous liability, Samsung would be completely out of the running for the competition. The transaction was completed to my complete satisfaction.
