The rewind is slower than I was expecting. A little stop-start and difficult to know sometimes if it is actually working. I guess you just need to be patient! The installation is straight forward but the attachment to the wall comes with bolt head screws rather than cross head screws, making it impossible to fix without a special drill bit which few people will have in their toolbox. I certainlt didnt. An adjustable spanner as per the instructions doesn't work. So, I used 4 of my own super large conventional screws instead. Job done!
