I pay exactly $1 dollar for a small button cell keychain pointer and it gives me about a weeks worth of play time with my cat before I just throw it away because its cheaper just to buy a new one. This is with a cat that goes absolutly crazy for them and will not stop from morning to night. As far as the dot I can see it 50ft down the hall spot on. Is your purpose to play outside with your cat and does your cat like them so much that batteries are that much of an issue. I know you have to press a button but is it that much of an issue? What ever you prefer is your absolute right but I feel so much safer using the ones I do and just get 5 for $5 and throw them in a draw, and i'm thinking the pet smart ones are the exact same as the dollar store ones or very close. What ever you get its still fun to see a cat play:crackup:
