:( :(

I expected so much more from this for fault finding. If your a installation engineer and want to move over to breakdowns don't bother with this. Some good material but other wise quite basic. No offence to mr combi, I'm just dissatisfied and wish I had saved my £19.99.

Developer Response ,

Thanks for the feedback, pricing is obviously a significant factor in making a purchase and we're sorry this didn't meet your expectations. Creating an application such as this takes a considerable investment in time along with filming, production, development and hosting costs. We have positive feedback for our courses and DVDs from hundreds of engineers, over many years, so it may just be that your abilities are higher than this content is aimed at.

Good App

I’m a year into my boiler repairing journey and the videos helped and gave a few extra tips I’ve not been taught elsewhere. Teaches you about testing with a multimeter
