## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly
*by J***1 on 11 October 2024*

I've used a lot of these now and I can't fault them at all. Being in the trade and installing heat pumps and a/c for a living, these come in very handy. Originally bought as a gadget for a hot tub I had at home to compare between an electric heater and hot tub heat pump for running costs. Worked so well I've started using them in customers houses now. Easy to read, easy to install and so far can't complain in terms of quality or reliability and I'm sure I would have heard back from unsatisfied customers by now. They're not a DIY install as you need electrical training/experience to work on any fuse board etc but they're not difficult to install at all. Terminals bite securely, no lose threads or wrung threads etc. Buying more for another job as I write this. Value for money

### ⭐⭐⭐⭐⭐ Very useful for making your own energy monitor which is easy to read
*by S***C on 19 May 2022*

I am well impressed with these little units. The digits are very easy to read and it appears accurate. In particular it surpasses all the other plug in units which are often difficult to read especially in inaccessivle places and which are practically useless in the absence of a battery as their readings are los as soon as unplugged or if the power fails. These units retain cumulative energy usage and can also be reset manually when required.I bought two to make up my own energy monitors and needed a housing for them. Initially I bought two ASHATA 3 module consumer unit boxes. They are rubbish, flimsy, difficult to open and far larger than advertised so they are going back. In their place I bought two Wylex ESE2 enclosueres which are good looking and very sturdy boxes which will make perfect housings. Bet bit - they are only £3.55 each - incredible!! A bit of work fitting plugs/wantering sockets and I shall have two first rate energy monitors.

### ⭐⭐⭐⭐ Overpriced
*by F***N on 10 March 2025*

Good but there is cheaper than this. I would buy one from Ebay for cheaper
