Product review (5 stars): Impressive
So far, Im impressed with this Max Burton 6515. It is rated at 1800W. I measured 1755W with my  Kill A Watt  meter. Thats close enough for me. I have received NO COMPENSATION OF ANY SORT for my review and I would be the first to tell you if a found a flaw in any product.
.
Areas that could be improved:
1) Finer control in both power mode and temperature mode would be nice
2) The dial control is a bit finicky. I left a message with customer service to ask about it. They did return my call within 1 hour but were of limited help. Still, I am impressed that they returned my call.
3) It would be nice if the power level ( PL  mode ) went lower than 500W. Though  Temperature  mode can go lower, 500W is just not low enough for some types of cooking. PL 1 is perfect for quesadillas. To get lower heat than that, you have to switch to temperature mode.
.
Things Im impressed with:
1) Its VERY powerful. It brought two cups of room temperature water at sea level in a coated cast iron pan to a simmer after 1 min, 15 sec and to a rapid boil after 2 min, 30 sec.
2) Its nice to be able to get a low, constant and reliable temperature. You have to use  Temperature  mode for this but set to 100F ( non-probe ), it melted chocolate without burning. I let it run for two hours this way and the chocolate did not burn.
3) The case feels very strong and the feet have adjustable height ( screw type ) for stability.
4) The case is grounded. For safetys sake, ALL electrical appliances in wet locations should be grounded.

Tips and tricks :
.
Please, ALWAYS use a GFCI outlet for any electrical appliance in a wet location. The life you save may be your own !

The plug is for a standard 120Vac 15 amp outlet, however, during testing I did see some current draws slightly higher than 15 amps. Even though it will function on a standard 15 amp outlet, I recommend using a dedicated 20 amp run with 10 awg minimum Romex right back to the main panel. Thats how mine is set up and I've had no heat or voltage drop problems with it. Note that my equipment is NOT NIST traceable and is subject to error. I recommend waiting for my final review before purchase.
