Having searched builders merchants, agricultural merchants and similar for a solution to birds perching on timber 'doors' of our converted barn I sourced your company on the internet. I found the service and speed of delivery excellent and the product has cured my problem of unsightly bird mess down the front of our barn. Installation was very easy and so was cutting the spikes to fit under some eves. An excellent service and product. Peace of mind and no need to look at unsightly mess to the front of the home. No need for regular time consuming cleaning and painting.
