Critical Power Supplies Ltd customers report helpful support when choosing products, with one reviewer saying Chris found a suitable alternative after their first choice was discontinued. One reviewer was unhappy after being recommended a different UPS that proved unsuitable, had to return it, and was charged a 15% restocking fee plus return shipping; they say they were badly advised. Another reviewer felt well supported and happy with the recommendation and product, and one said Chris dealt with a delivery at short notice. A further reviewer said a stock shortage was put right, with options explained and quick delivery, and one described resolving problems as good.

Great customer experience. The product I wanted was discontinued, but Chris got in contact straight away and was very helpful in finding a suitable alternative.

Very bad experience I'm afraid. I had contacted the company regarding a UPS and after explaining what I need it for, was recommended a different unit. After it got delivered it turned out to be unsuitable for my needs and I had to return it. The company then told me they would keep a 15% restocking fee. So I've lost £270 + had to pay for return shipping. They companies response was "you should have read the specs". I feel I was badly advised and will certainly not use this company anymore. I recommend everybody to look for other shops with better customer service.

As a novice in the arena I felt well supported and listened to throughout the journey and am very happy with the recommendations and product I was given. Chris was excellent throughout making sure I was comfortable and confident in the approach and solutions delivered. I will add more about delivery if relevant once the products arrive.
