Rated 5.0 out of 5.0 by Great customer service from both Home Depot and Smarter Tools We bought this generator on last Thanksgiving sales and never opened the box after it arrived since the box was in perfect condition; so we were really disappointed after we opened the box in preparation for Sandy to find the whole air filter system was damaged. After call to HD customer service and our trip to local Home Depot, we decided to keep the generator since there was no generator left in the store for us to exchange and we needed one for Hurricane Sandy. The kind gentlemen in the repair and rental department took his time to look at the generator and told us it's safe to use regardless of the damage air filter system and that he would order the part and replace for us later on. So of course we had to use the generator when Sandy arrived and had no problem at all. The generator started on one pull and ran smoothly. We even loaned it to our friend after we gotten our power back and she used it for almost a week. 3 weeks after Sandy, I called Smarter Tools customer service department to order the part (since my husband found it's very easy to replace it and wanted to do it himself) and right away they sent the part to us without charge...What a great service..thank you Smarter tools. One word of advice though, please do open your box to check the product as soon as it arrives to avoid unnecessary inconveniences. December 10, 2012
Rated 5.0 out of 5.0 by Good, cheap generator It probably isn't a product I will depend on to run when the zombies come, but it works great for camping. Don't be silly, follow the maintenance and storage instructions. As a mechanical engineer, I can tell you, these ARE important! If you're handy, keep a basic tool set with you, unless it's a generator issue, you can probably get her running. Overall a cheap buy. Easy to start (my wife can do it). Change the oil frequently! Lot's of chips from Chinese machining. Don't run it at full load! It's not a Briggs & Stratton. January 28, 2014
Rated 4.0 out of 5.0 for the money this is a great little generator We got this generator to run the essentials of our house during power outages (fridge, freezer, gas furnace fan), it works great. One thing to note, this generator (like most portable generators) has a floating neutral; meaning that the neutral and ground are not bonded in in the generator; this can cause residual current in the neutral line when using a long extension cord. Some electronics don't like this and will detect a reverse polarity. If you are using this generator to feed your circuit panel, this is not an issue (the neutral and ground are bonded in the panel). It took me a while to figure out why it wouldn't run my power vented hot water heater (which has some advanced circuitry) so I thought I'd pass it along. November 1, 2012
Rated 5.0 out of 5.0 by Fantastic price and super easy to start I opened the box, added oil, turned on the fuel, flipped the on switch and gave it a very gentle pull just to see how easy it would be to start. I waited 1 second to let fuel get to the carb then gave it one more light tug (about 1/2 the effort of pull starting a push mower) and it started right up. I allowed it to run for 10 min then I added a 1200 watt heater and 2 full size refrigerators (both running at the same time) and the generator did great. I posted a vid on you tube showing it hooked up and running under load. July 14, 2012
Rated 5.0 out of 5.0 by great back up power When my power went out for three days, this thing worked great. I plugged in my refrigerator and used it to power up my camper and run the slide outs. It ran for three days while I live in my camper until the power went back on. And I only paid $200 for it! October 1, 2015
Rated 3.0 out of 5.0 by Service locations My only call out is the service stations Smarter Tolls is associated with. With in the first year I had a problem after less then 20 hours of use. Smarter Tool quickly sent a replacement part for what I thought the problem was but it did not help. I had to take it into service under the warranty. Smarter Tool is not associated and is limited to companies they have service contract in fact people they recommended didn't even know them. After a month I had my generator repaired and returned without a charge but it was a struggle. Smarter Tool stands behind their product and their customer service is good, they just need to start associating themselves with better service stations October 13, 2013
Rated 5.0 out of 5.0 by best money i spent on a generator i bought this generator a year before sandy came around and never really used it just started it every couple weeks let fuel drain out and kept it treated with fuel treatment. then sandy came i filled it up with gas got it ready. very easy to use not to loud and i had no problems i ran it threw an outside breaker box which feeds my main panel in the house all properly installed and being only 110 it ran my LP furnace fridge microwave lights in the house 2 TV's and cable boxes kept my internet on and charged my phones the best treat of all i ran it from 3am till 4 the next afternoon and still didn't run out of gas i did shut it down let it cool down for a couple min fueled it up and away she went it was the best money spent and i fill i allready got my money out of it just by saving my grocery's and staying warm during the storm October 29, 2013
Rated 4.0 out of 5.0 by Great Buy !!! Purchased two of these generators one for myself and one for my parents. They arrived quickly and I was able to start them while holding a can of soda so they are very easily started. The noise level is moderate and I love the features. The only draw back is that one of the generators started pouring gas when we started it upon further inspection the gas supply line had come off. Both units seem to have the same problem the hose is an inch too short, so I made a trip to the local hardware store old hose in hand so they could match it up and it was $1.50 for two new pieces of hose and stronger clamps and then we were back in business. I hadn't seen this issue written in any other review but a word to the wise both of mine had it. (bad batch or lot ?) it takes about 5 minutes to repair So just check it out at least it might save you some downtime in a much needed time of power but overall I would highly reccomednd it .
