I recently purchased a Vectron inverter from an online store called livesustainable.co.za. After just one night of use, I noticed a major issue — the inverter drained my batteries significantly more than my previous inverter, despite running the exact same load. Clearly, something was wrong. I immediately contacted the store to request a return and refund. To my surprise, they flatly refused, saying that because I had used the inverter, they would not take it back. This is completely unreasonable — how else is a customer supposed to discover a fault without actually using the product? This experience has left me with an expensive inverter that is of no use to me. I expected far better service and support from a business operating in such a critical and technical field. Instead, I was met with a rigid, dismissive attitude and zero willingness to resolve the issue. I strongly caution others against buying from livesustainable.co.za. If something goes wrong, don't expect help — just excuses.
