I have used it for 6 months, there are no issues. It was used in the previous office setup and is no longer needed in the new office, so I am selling it. Warranty cards for both are available. I will sell them for 2,000 Taka each, totaling 4,000 Taka. I bought them for a much higher price, but I am selling them now so they don't get damaged sitting in the office.
