I purchased the Vessel Candella10 Lamp set at $400.00 - it comes with a one year warranty. I love the set, but had a problem with the lamp battery bursting (it happened to me twice). The first time it happened, Vessel was all over it - they replaced the defective lamp within 1 or 2 weeks. The second time it happened, however, Vessel customer service was no where to be found. It has been 5 months now since I reported my 2nd burst battery in the lamp. They will not return my phone messages (over 10) or reply to any of my emails (another 10+). I don't know what the problem is ... all I can say is KEEP AWAY, at least until they get their customer service act back together again.
