Spot onReviewed by Ecoombes on 23 Jan 2024

Prompt service and dispatch although DPD did muck it up, said they tried to deliver, wife was in all day, then said they had left it at our local post office but had actually left it at a post office some 5 miles away.


Expert AdviceReviewed by Lesley_smith_1 on 15 Dec 2023

The stat I purchased works perfectly but my review is about the expert advice I received from Rob. I had previously bought the wrong stat elsewhere but could not find out why it wasn't working. I emailed Eco Wizard with my phone number and before too long I got a call and actually spoke to someone who could explain what the problem was - something I was unable to find out in all my hours trawling through the internet! Thank you Eco Wizard & thank you Rob.
