I went to Aileen for custom blinds for my new condo. I ended up going with Hunter Douglas blinds, one that were roller blinds and one that was a motorized duette blinds. While the blinds themselves were great and the frontline customer service I got was good, there were issues post-sale. The in-store customer service I got was helpful, the guy who came to do the measurements was great and offered recommendations on colours and the guy who installed the blinds themselves did a good job, quick and courteous.
But compared to non-brand name blinds at the big name store you're probably aware of, my custom blinds took 4 weeks to come and an installation appointment set up. The other place you're probably aware of, granted they aren't Hunter Douglas brand, can be ready in fast as 48 hours. The price is also hugely different as a fellow neighbour of mine in my condo with the exact same window measurements had their blinds done for about less than half the price (comparing apples to apples, just the roller blinds in this case. Not the motorized duette blinds).
I like the blinds themselves and majority of the service was good but it bugs me to no end that I had to wait so much longer than he did and he also got it for so much cheaper, by going to that big name competitor.
