The actual sales side is quick and efficient and goods are delivered on time and as promised. The after-sales leaves much to be desired. Had issues with orders and it took the senior management to get involved to rectify and resolve. In the end, I got the result that I wanted, albeit being left with a sour taste. I will not be returning. My advice to Nitrotek: treat a customer as you would like to be treated yourself. In the end.......the customer has a lot more clout than you'd like to think.
