I tell you one thing I've noticed with most all off these Chinese led companies. Some amazing customer service. I mean if your in the u.s. and have the late night time you can negotiate prices for hours. I'm not saying don't accept the first offer but it might benefit you to do so. If your using ****** and they try to charge you "bank fees" ask them why. Read ****** closely. Bank fees are sellers responsibility. They then have to knock that fee off the final bill. Saves a few bucks.
Hahah, that's basically how I was last night up until almost 4 in the morning try to negotiate if I should get two smaller ones for more customized coverage or just the one 400w as a single unit. Hope next time I can get more information and lower price but still gonna read up on the company you posted.
