It depends what you mean by easy. Heres the process in effect :
1) You need to measure your windows accurately. Easy.
2) You need to check for clearance of handles etc. Easy.
3) You need to measure the depth they will sit to so you can order the correct set of clips. Medium difficulty.
This is all explained on their website, but I found the last part a little tricky, just that nagging worry you may get it wrong. However it wouldn't affect the main part so if you did mess it up then its just some new clips you would need.
Edit, actually on this point, it could possibly affect it. Just go slow, you should only need to do it once. There are standard depths so I measured then check to see if I lined up which I did.
When you receive them they are flat packed, so you have 4x lengths of metal blind rail, with the corner sections.
1) Empty it all out and check which is which if you are ordering multiple blinds. Easy but keep your measurements by window if you have multiple in very close dimensions. Easy.
2) Put the blind together. Medium/difficult. Depends on the size and if you have help. The corners are stiff and your trying to force some roughly cut metal ends into them. I started just scraping off the ends a bit to remove the worst "swarf" which seemed to help. You need to wiggle them a bit. Medium/difficult. Just take your time.
3a) Insert clips to window. I found easiest way was to hold blind to window, mark with a pencil a little line where you needed the clips (2 or 3 per side) and then put blind down. Easy.
3b) Depending on your seals you may need to lubricate them a bit, or may be able to just slowly push them in. Once you have done the first one you will get the hang of it. After the first I was inserting all per frame in under a minute. Easy.
3c) Raise blind to window and push it into the clips. Easy.
Bear in mind if you go for large slats they have to stick out more. How far they stick out is a combination of how deep the plastic is around your glass and how wide the slats you choose are. We went for the smallest slats as we wanted them as close to the windows as possible.
We already had plantation type blinds and have in effect now doubled up in our bedroom.
They are really good this time of year however when the blind follows the window, so if you open it a bit the blind doesn't get in the way at all. The whole blind in the way or being basically unusable thing goes away.
Hope this helps.
