Had it 2 weeks now. EZ to start. runs smooth and relitively quiet. I ran a couple items on it just to test. Will run larger items (refrigerator), and RV in the next couple weeks to really see how it performs. But for now I am very satisfied.
This is a very early review, since I just received my 1Gen4500 yesterday. I made the purchase because of the low noise level, long run time, and data center for tracking run time, power output, remaining fuel, etc. I unpacked the box, connected the battery, filled with oil and gas, pushed the start button and it fired right up. Very easy, smooth and quiet just as advertised. I will give more information as things progress. Very happy so far, and feeling much more secure amid power outages.
