Extremely bad! Lasts exactly one year in daily use if not watered. Another bracelet going. The previous one when I bought a year ago so the seller claimed that these have no warranty. Now, a year from now, we are in the same situation again. I noticed that a 2 year warranty is mentioned here. Well, there are no receipts stored that could open up for the seller. And it's not the fault of this online store when I haven't bought it here, but I don't recommend a wristband for everyday use, Sunday watch maybe ...
