AD instils confidence in their products, with videos and customer testimonials of their products in the controlled environment and in the field. AD back their products with generous warranties, indicator of performance of the products. The pricing is mid range and for what you get, in terms of construction components and fit for purpose assembly, this increases the value of the products. Great team to deal with, prompt communication and delivery via courier. The courier costs are reasonable for the bulkiness of some of the deliveries. All these aspects instil confidence for myself to invest in their products.
