This is from the BBB

I purchased my welder on 3/16 and didn't get an opportunity to use it until June. It worked for approximately 1 hour before it broke. I shipped it to the Everlast service center on my own money on June the 16. It has been there ever since .
It took until 3/10/17 to get resolved?

Purchased via Amazon on August 24, 2015 for $1,216.99. Machine failed on November 2, 2015. Obtained return authorization from *** at Everlast. Shipped back at my expense for $153.67 on March 2, 2016. Heard nothing, so called on June 21, 2016 - 3.5 months later. They told me it would be done by July 1, 2016. Heard nothing, so called on July 15, 2016. They told me it was next on the bench. I just got done reading through the other BBB complaints and it sounds like this is exactly the problem that others have experienced. We had to buy a different Plasma cutter from another company to get us by. My business has LOST money since we have been down a Plasma cutter. Not to mention that we have spent $1,370.66 between the purchase and shipment to be repaired. This is unacceptable.
Again it got resolved on 03/10/17

I purchased an Everlast powertig 210EXT tig welder in March 2015. The reason why I chose Everlast was because of their advertised 5 year warranty. My welder stopped working January 27th 2016, I called technically support on February 2nd, 2016. I spoke to *** at everlast tech support who instructed me to mail it in for repair- I sent it in that day. I called two weeks later in Mid February to inquire on the status, I spoke to *** again. He informed me it is estimated to be ready the second week of March "We are backed up 4 weeks". I called in March (spoke to *** again) and was told it is estimated to be completed now the second week of April. That time again came and went, I called again last week and again was told by *** "not ready". I sent my welder in February 2 2016, *** at Everlast confirmed receipt on Feb 9th, it is now May 3rd 2016 and my product has yet to be repaired under their warranty agreement. I have called multiple times and spoken to *** at Everlast. Waiting more than 3 months for repair of a product that in some cases represents someone's livelihood is unreasonable and I am unable to find a resolution for this matter.
This was also resolved on 03/10/17 I guess you have to file a BBB complaint to get your welder back?

I could not find any BBB complaints against Esob.
