Backup UPS Power Supply 1500VA 900W Battery Backup Power with 4 Outlets and LCD Display, Suitable for Home and Office

Very easy to assemble and understand

the instructions were hard to understand but product worked well and was easy to use cheap strap replaced with better one Over all pleased with it

I put the collar on 30 because it says it's meters so that's approximately 90 feet which is the lowest it goes , but after getting 25 feet (at the most) it started to beep, then I set it on 60 meters and that is the 2nd notch , supposedly 180 feet? I got about to 45 ft and it went off , so make sure you test where it actually is going to be limiting your pet to because we couldn't even get out of the house with it until it was set at 120 (when the receiver was really only about 40 feet from the front door ) it beeped on the lowest -30 - 1/2 way to door (20-25 ft)then at 1 up - 60 - as soon as we got to the end of the stairs to touch the grass outside (so 40-45 ft ) settings are way way off on mine. Hope this helps !

I RECEIVED IT BUT THE TRANSMITTER WOULDN'T CHARGE. I SENT AN E-MAIL TO THE SHIPPER ON SUNDAY AND STILL HAVEN'T HEARD BACK. INSTRUCTION BOOK IS HARD TO UNDERSTAND.

It just kept on zapping and beeping. When putting the desired range I wouldn't move but 5 feet before it started going off..

Horrible system.. And was broke

Read thoroughly. Not a rechargeable transmitter

I had to return the item, the transmitter would not charge. No number to contact customer service.

chargable battery will not recharge
