I made enquiry via Live chat about the product I eventually bought and my questions were answered by John very quickly and succinctly. He promised further details by email which duly arrived. I was so impressed by the quick responses I ordered a Cyber Power UPS. The price was excellent too. To cap it all, my purchase arrived the very next day at 1307hrs after placing the order at 5.02 pm the previous day! To all at Una Technology a big thank you for such great service and very well done. If you are reading this review, I don't work for Una Technology-go right ahead and purchase, you will not be disappointed. This is my first purchase from them, won't be the last!
