Good that you can see the products on their internet page, allowing us to control our search and ask questions when we wished to, whereas most of the other companies wanted you to call or leave a message for them to contact you (only one of 5 companies I did that with actually contacted me back, and that was 4 weeks later!). Aspire responded well to any questions we had for clarification. Bi-folds (Revere White 4800mm 3+3) look like a very good product and now that they are installed look great (our builders and fitters were very impressed with the quality).
