Very easy to get started and to setup the chipolo. The only problem is, that they can't handle water. Even though they got extended time to fully dry, I was unable to connect the it again.
Got 4 of them, very efficient. One for my bike, one for my wallet, 2 for some bags . Tested with friends taking them away from me. Refreshes location every 10 minutes approximately in big city like Paris. Very satisfied.
