After more than 7 years, the battery is probably worn out at the end and the chest strap. So I'm going to have to buy a new, but will, in the hope that the successor work just as long again choose this product.
One point I draw from, because you can not change the battery yourself. So much clean environmental responsibility should be in there today.
I buy the product anyway, because I at 7 years use of the Arctic with another product that, if necessary, less long stops and must be replaced more often or more frequent battery replacement required, probably not going to produce less waste.
