Poolguard Inground Pool Alarm

I have been looking at purchasing the Poolguard Inground Pool Alarm. Does anyone have any experience with this unit? Does it work with the pool pump running or just in still water? Do you have many false alarms?

Anyone else that has a pool alarm that they are satified with?

Thanks,

Riles

I just received mine in the mail yesterday. Waiting for my IG liner to come so I can get my pool filled. It was the only alarm recommended by Consumers Report and it works fine with the pump running, so they say.
