Rated 4.4 out of 5 by 66 reviewers.
Rated 5.0 out of 5.0 by I just used it for the first time. Worked great Worked great except it took 4 pulls to start. That may because I turned off the gas to shut it down a couple of months ago when I first got it and tested it. I had a smaller generator before and had to turn off the lights to run my wells. Now when the 3500 watt wells kicked in there were no hiccups. Also I was able to use my Advantium microwave. I turned off the well breaker first to be safe then turned on the microwave. The lights dimmed but it worked. It is nice to be able to have lights, TV, flush the toilet, and cook. Now I am only missing the 4500 watt hot water heater for long outages. November 28, 2014
Rated 5.0 out of 5.0 by Runs whole house Just hooked up my new STGP-6500 and it runs the deep well pump, refrigerator, oil furnace, and assorted small lighting and electronics loads without even breaking a sweat. Actually sounds like it is only at idle as far as can tell. I am tempted to try my electric oven and or dryer as well. Unit seems very well made and was easy to set up and get running. Very Happy and would definitely recommend. December 24, 2014
Rated 4.0 out of 5.0 by Easy set up instructions, started right up. Great! Easy to put together. Just a couple parts, handles tires, etc. and it started right up! Runs nice and smooth--no "hunting" when under light loads. I spent a little bit of time looking at the engine size (cc), run time, peak load, features (like a case iron sleeve), and price. I emailed the smarter tools folks with a question prior to purchasing and was delighted to get a real person and prompt response. I then settled on the Smarter Tools unit. I only gave it 4 stars because Ive only had it for 3 months. November 19, 2013
Rated 5.0 out of 5.0 by Helped us battle Sandy We were already out of power for 36 hours when I found out that the Downingtown Home Dept had received a shipment of 170 of these (no one else in a 50 mile radius had any generators). Got it home, took it out of the box, added the wheels, added oil, and then gas...and to my surprise it started on the first pull! My luck is always bad, so I figured it wouldn't work at all. I was able to run 2 fridges, 1 stand up freezer, a hot water tank, a 47 inch widescreen TV, DVD player, and a number of lights without any problems what-so ever. I have recommended this to friends and neighbors. November 2, 2012
Rated 4.0 out of 5.0 by defective wheel When I bought the generator it came with a defective wheel and 3 weeks later still no replacement yet, nor any status update. April 8, 2015
Rated 5.0 out of 5.0 by A lot of features for a great price. I got one of these last week. I pulled it out of the box, added oil and gas, and it fired right up on the first couple of pulls. It has plenty of features that are not available on generator in this price range. I've hooked up a few items around the house (heater, refrigerator, window AC unit) and it handled them all without fail. I am confident that this unit will do the job when I need it. July 29, 2012
Rated 5.0 out of 5.0 by More than satisfied Started on second pull...Easy set up...Not as loud as other generators. December 25, 2013
Rated 5.0 out of 5.0 by This generator passed a rigid test durnig Hurricane Sandy This generator was used continuously for over 140 hours during Hurricane Sandy. We were out of power for 13 days with only recommended oil changes performed on this generator. Initially this generator was purchased to operate my sump pump only but it powered many appliances including our furnace during this outage. Kudos to Smarter Tools for manufacturing such a durable product. I now simply start it monthly to keep it ready for the next storm. September 19, 2013
