The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit and high or low battery voltage. The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries.

Pretty durable, ears not so much
Pretty good but chewed through the ears in just a few minutes. The body seems more durable. We have a goose/duck from this brand that has held up extremely well.

Another one bites the dust!!
Another one bites the dust. It looked like it was gonna be strong enough for our new puppy. We adopted a border collie who is about six months old. This was supposed to be durable. Lasted about a week. Might be good for older dogs. I wouldn’t recommend.

Too expensive
This dog toy did not hold up due to poor manufacturing in my opinion.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!
