I have an electric window that can only be used manually, it’s a disgrace and l have paid experienced people and they can’t even get it to work by your so called system and not revealing that further components are required after it is purchased which you only discover bit by bit and when you think you have got it to work by your instructions it still does not work.I am assuming it will only work if l have to pay one of your employees to come out and fixit. ,if it’s fixable.if l had known that it cannot be installed by your instructions l would not have purchased the window if l had known in advance that you do not supply all that is needed in the first place to actually be able to use the window opening and closing mechanism.however l am still back where l started nowhere except incurring extra expenses.
Easy to find the product I needed for the velum windows my house has. Very easy to fit and they work perfectly for our needs.
Outraged to find that the all the product essentially was: two foam strips and a small tube of grease/oil. The instruction sheet did not cover the model it was destined for so had to phone in (struggled to find support number) just to get the info. On an upside the easy video link to solve the problem was clever and helpful. But waited ages for such a simple pre-packaged / off the shelf product. Outrageous cost. Finally to replace the paded strip from the vent flap is still proving very difficult as the glue (far stronger than the foam it secures) is impossible to remove successfully. Some release agent would at least go some way to justify the cost: £41.00 for a couple of simple foam strips. Outrage.
The screws require a specialist tool; common UK screwdrivers do not work with them. You should provide a tool or change the screws.
