I've had both systems hands down the alpha. Way more features plus you can get there attention when you need to.

Do they make them for lap dogs???? Did you let the grass grow up and you need a collar to find fee fee in the yard?????

You just load up your sheep hounds and we will play, want it b on the deers though. I'm not scared, YOU????

I bet I can make one of these collie dogs run a nanny and prolly hold it til we get there. No I aint scared.
