I like the pink color, but it's not as bright as the red collar. It has two settings: solid and blinking. I haven't had to recharge it or change batteries yet. (I can't even remember what method is used to recharge.) We go on a 20-30 minute walk every night in the dark, and we've been using this collar for about 3 or 4 months. The collar is very long and can be cut to the right size needed. I cut it so that it is just long enough to where I can easily slip it on and off my pup's head when needed. I never use the actual fastener.
