Started on first try after servicing. Tested with various machinery. Worked great. Trucking company kept me informed of delivery status. Arrived timely.
Recently received our generator. The customer service and shipping process were great and we did not experience any quality issues. We're very happy with our new generator and hope to get many years of use from it. Thanks so much!
Thank you good price . Quick shipping
Just received my Yamaha from National Supply. Was a little hesitant to have it shipped across the country but it arrived in perfect condition. It was well protected in a crate surrounded by metal. From my first conversation with National supply to delivery in my garage everything went like clockwork. Started immediately and very quiet. Would definitely recommend this generator and use National Supply again.
very quiet, works as advertised. a little on the heavy side to take on our RV.
Used it this weekend and it is so nice to have the generator close to you and not even hardly able to hear it very Quiet
Ran it 11 hours straight and used less than a half of a tank of gas was just pulling fans and a couple Rc battery chargers so wasn't running much of a load on it but was still impressed.
And national supply was awesome to deal with and can't find a better price any where Larry was great and the other 2 people I talked with sorry don't remember there name but every one was great will definitely be buying from them again
This generator is great. Quiet operation and handles all of our equipment in our concession trailer. The staff at National Supply were professional and eager to help in assisting in sizing the needs for a generator. Quick delivery! Thanks National Supply!!
I've only had the new generator for a couple of weeks now...however, to date, I wish I would have purchased it years ago! I ordered it on line and the unit was at my house the next day! It was extremely easy to unpack, install the battery, oil and gas and it started up the first time! Put a few different loads on it and they were handled NO PROBLEM.
Yamahagenerators had the best price by far that I could find on the EF4500ISE generator plus free shipping and 0 tax! Shipping was fast and I was very pleased with the way the generator was packaged and secured on the pallet. Left CA and arrived in East Texas with nary a scratch. I would not hesitate to buy here again.
