Quality: what a fantasic package starmax has provided. Excellent quality on the internal parts, cables,250a fuse dc isolator, caseing .I would reconmend getting the base with wheels as it is very heavy once construted. Exceelent pakage all round. Service: If i could give 10 stars i would as that has been my experience during and in after sale service and communication. My contact was a fantastic person called Lucy who i never felt i was a hassle to ask her anything. Always polite and quick to respond, In transportation within Australia the freight company had a accedent and unfortunatly damagad a box of 4 cells. I notified Starmax and provided proof of damage within a few days new box of cells where being tested to replace transported damaged cells. You really connot ask for more. Highly reconmened company.
