Reviews for Malibu 300-Watt Power Pack with Timer and Ground Shield #ML300RTW:
For a 300 Watt transformer,this is a great value. I really wanted a transformer without the timer since I control my lights with an X-10 system. However,I couldn't find a better deal on a transformer without a timer. It was easy enough to pop this open and bypass the timer with some simple rewireing. Only took about 15 minutes. I gave it a 5 star rating even though it doesn't have a switch that could turn off the timer and provide a manual On/Off capability.
Decent quality steel case.
Mechanical timer.
I had the Hampton Bay 300 watt model....DO NOT BUY HAMPTON BAY TRANSFORMERS. CUSTOMER SERVICE IS VERY BAD AND THERE IS NOT EVEN ANY WARRANTY OR CUSTOMER SERVICE INFO IN WITH THE PRODUCT,as I found out when it broke and going to Home Depot for help was a joke. Anyway,I am happy so far with the Malibu and it seems that it has a bigger transformer than the Hampton and the overall construction is better. Just to convince you of how bad the Hampton Bay customer service is try doing a search for them online,you'll see.
