I bought 2 identical blinds. 1 I fitted with no problems. The other has a manufacturing/assembly problem with the side rails. Customer service were very helpful and after a video chat replacements were ordered. HOWEVER I feel very disappointed that the delivery date for the replacement is estimated at 26-Aug. I feel this is an unacceptably long time. We bought the blinds because of the need to block out the sun in this extremely hot period so I'm sure you can imagine why this delay is so disappointing.
