Great generator for the price
By from mount forest on Jul 12, 2015
After doing some research we bought this generator as it was a good price and it had enough watts to run what we wanted it too at the cottage, also we wanted something that was on the smaller side so my wife and I could take it in and out of the boat with ease, the weight is perfect even with a full tank of gas and it was quieter then I though it would have been as it doesn''t have idle control, it would have been a nice feature to have but then the price would be more, all in all its a great generator for the price and it seems to handle a little more then what its rated for too.

Generac 3300 Portable Generator
By from Windsor on Mar 29, 2015
Casual Do-It-Yourselfer
Was easy to assemble as per instructions, added the oil and gas, and fired up on first pull. After watching an info-mercial one Sunday morning, I focused my buying search on Generac. This model, which is exclusive to Lowes, was the one I wanted..... so, if the hydro goes out this spring, I will be ready!

Customer Service is AWFUL!
By from Clayton, NC, USA on Feb 21, 2015
I purchased this GP3300 Generac generator and when assembling it, I noticed that one of the leg mounts was missing. When calling Generac I got the run around and was even told it would be easier to go buy the missing piece rather than open up a case with them, which if I did, I would have to provide photos and "concrete evidence" that I what I was saying was true. Steer clear of Generac, or buy at your own risk! I did decide to try and purchase the part from a third party. If that is a headache, I''m returning the generator.

Very "KNOWLEDGEABLE" salesman demonstrated the Generac generator I had asked to see. I was told this company, GENERAC, set the "benchmark" for the generator industry. The salesman pulled the generator out from the display shelf ... with ONE pull, the generator started !!! I "IMMEDIATELY" told him I WANTED it !!! ALSO ... I''m SO glad to have this opportunity to tell others that I am MOST grateful and THANKFUL that Lowe''s offers the 10% discount to disabled veterans and to active duty and to retired veterans. I will ever be in their gratitude !!! Hard to describe this feeling of "appreciation" from such a generous nationwide business !!! THANK YOU LOWE''S !!! I''ve wanted to say THIS for many years !!!

Not really 3,300 Watts!
By from Palmer, Alaska on Dec 19, 2014
This is my 2nd Generac generator (first was a GP5500 that lasted about 550 hours). After a month''s use, I am extremely disappointed. It runs well and fires without too many pulls- even at near zero temperatures. My problem is with the circuit breaker. Though it is rated at 14 amps (and the entire generator at 3,30-watts), it trips at far, far less current than that. I live off-grid, and this is used to charge a battery bank through my house''s inverter. As such, I can precisely control how much current the charger pulls. Want to know when it trips the breaker? 6 amps. A trip to Generac''s website finds many, many owners of this model experiencing the same problem- some are unable to run even 1,000-watt appliances without tripping the breaker (on a 3,300-watt generator!). I''m going to try and return mine tomorrow for a GP5500- at least its 20 amp breaker works!

Good general purpose generator
By from Asheville, NC, USA on Nov 24, 2014
I looked at this initially because Generac is a top name in generators. The price was also a big plus, and overall I am happy with the product. Great design and very compact. The one thing I am VERY disappointed about is the power quality. None of the sales product information mentioned it. And I ASSumed (my mistake for not researching more) that a Generac with a 240v output would run anything. It won''t. Instructions say do use for any sensitive items (TV''s and other household products requiring smooth low distortion power) and after doing the research I found that THD is over 5%. So for non electronic power tools, lights, small heaters, and other simple items it is great. But don''t expect to power your fridge, microwave and TV in a power failure.

Started First Pull
By from Alabama on Oct 27, 2014
This started first pull out of the box. I ran it for 10 minutes let it sit for 30 minutes and the second pull it started up immediately. I tested to how much it would run and this ran several household items, very powerful for a little unit. It is heavy so up and down stairs is a bit much but very happy with this purchase.
