I placed an order in extreme haste to take advantage of discounts that were about to expire. This was on a Saturday and out of business hours so I couldn't obtain answers to a number of questions that I wanted to ask about the product. Consequently I spent Sunday conducting my own in depth research which established that the offering, whilst undoubtedly excellent, had certain disadvantages compared to that on offer from a competitor. I should add in all fairness that the competitor's offer didn't meet ALL my requirements, some of which WERE met by the Boundary alarm system but on balance Boundary were just edged out. I cancelled the order via their out of hours chat messaging but unfortunately the correspondence was not picked up in quite enough time to stop them packaging and despatching the alarm system although they managed to recall it from the carrier before actual delivery. However, they were extremely understanding and helpful and immediately refunded the payment. We all have our own different requirements and priorities when evaluating products and I would again emphasize that for others the Boundary system may well come out on top. Their business model is first class and I wish them much success.
