After using RGO blinds around my company's workplace for as long as I can remember, we decided to give them a try at home when renovating our top floor. Dealing with the company was easy and painless (they are a pretty major corporation though, so a certain degree of professionalism was expected — and we definitely got it). The blinds arrived and were installed without a fuss, and the product is great (although not cheap!). Our heating bill has gone down significantly (we ended up going with the honey comb blind design, which provides an insulating pocket of air between the window and the room). The savings on our utility bill will definitely make up for the cost in the long run, though.
All in all, would recommend the company!
