Great product and good advice from CPS Ltd for an UPS Have been considering installing an UPS to protect my home PC and had several informative & helpful on-line conversations with CPS's technical support who advised me of the various options. Purchased and the 800VA unit arrived in <48 hours and now up and running. Now I can (hopefully) rest assured that when the mains power goes off, my PC is protected. JPNH

Excellent service and very good pricing I have very recently purchased a 12V battery for my rather ancient but still very serviceable Belkin UPS from Critical Power Supplies. Their website was very easy to navigate and I found the battery I required withput any problems. I purchaed the battery which arrived two days later, in perfect condition and most beautifully packed. The price of the battery was most reasonable, being cheaper than a number of other sites I'd visited during my research. I give CPS five stars for both quality of service ( I was notified by them of each stage of the battery's journey!) and their professionalism in pricing and packaging.

Just how ordering on the internet should be Buying an item that you can't explain is pretty difficult, but the combination of an easy to use website, product specific search and free delivery made buying from Critical as simple as it should be. Thanks Critical.

Above and beyond.............. As an ignorant domestic owner of one these systems supplied by Critical Power I had no idea of how to deal with it. After my system was inadvertently powered down by a non-related fault in the equipment it provides back up for, I had no way of knowing what to do to get it going again. Critical Power came to the rescue, even sending me software, leads, etc to run diagnostics, without any prior dealings with them. They also came to inspect the system voluntarily. Impressive to get such great service in this day and age.

Did everything right Being ignorant of the product I relied heavily on the advice given. This was given willingly and in a friendly manner. Delivery was exemplary and I was kept informed of its progress. Best of all everything works after 4 hour power cut.

A GOOD & FRIENDLY SERVICE I CAN TRUST I ordered an Eaton UPS from Critical Power Supplies to replace my old and unreliable Belkin UPS and it arrived within a few days but when I tried it I discovered I did not make the right choice. I contacted James who sympathised with me and worked together to find a suitable model for my needs. The courier arrived the same day believe it or not to collect the UPS I ordered and the replacement Eaton UPS was despatched immediately and arrived within a couple of days. The replacement UPS suited me just fine . I feel a company that provides a good honest service deserves some credit and here it is from me. Looking for a UPS? You can't go wrong with Critical Power Supplies in my experience

Item arrived in 2 days This is a company that does a lot more than sell replacement batteries for UPS, but I found them while searching for replacement batteries and chose to use them because they sell manufacturer genuine parts, not cheapo copies. I quickly found what I wanted, ordered, paid painlessly with PayPal and 2 days later my item arrived. I'm very pleased and have no hesitation recommending.

Very fast turnaround. Arrived next working day. Shipping a bit expensive Very happy with speed of turnaround. Item arrived next working day (bank holiday was on Monday). Delivery cost was a bit expensive for a low value item though.

Recently found that my Yuasa battery, which powered my golf trolley had given up. Upon searching the web found your company, which was extremely helpful by way of the "chat line". Ordered the replacement, which was delivered 48 hours later. It was cheaper that your competitors and I thank you for the excellent service.

Order from these guys without really knowing what I was looking for, opened a chat box from the site and was surprised to find a human on the other end who could advise what I needed and links on the site to purchase. Placed my order at 23.00 and it arrived next day without paying for next day delivery. Next day thought I would chance my arm and once again asked a question, answer was immediate as was delivery next day again. Recommended my company look into using these guys brilliant service and turnaround time.
