I think the 10 days shipping is very poor and should be improved, as a past resident of France I know what exactly what the problem is... the French ways!.... it didn't move at all over the weekend, but when it comes to the UK it was delivered on a Saturday. Plus the first time I came to use one of the blinds... the top cover came off and I had to remove the whole blind kit to refit it, plus the system of fitting the top cover is very poor and not at all very rugged, I had apply some bonding agent to hold it more secure, so a job that should have taken 30 – 45 minutes actually took 3 – 4 hours. Plus your fitting instructions are very poor, particularly to do with pairing 2 separate blinds.... especially for my model, in-fact I found out how to do it using Grok AI.... now they work very well.
