Great replacement cap for my Purist water bottles.
I have really enjoyed using the Range Extender. I appreciate being able to just plug it in when my bike battery is getting low and feel confident I can go another 20 miles!
Satisfied with the watch, quick shipping, pleasant price.
Amazing cycling computer. Was shipped quick and great delivery.
