Completely different league than gen 4. Comparatively more powerful and faster. Finally, an assembly where you don't worry about the lock falling off.
I had a previous version that was significantly weaker than this one, and it couldn't open heavy security doors.
This version significantly improves both speed and power
It's addictive, getting rid of the keys,
Intuitive, easy-to-understand app
I don't know about anything

The unlocking/locking is so loud that it wakes up a sleeping child behind another closed door. Even in slowest mode. The "open door" function is even louder, so even the neighbours know you're home.
beautifully crafted
I was assembling for the first time, yet it can be done in 30 minutes

If you want a lock that stays firmly on the liner, this is definitely NOT it! For commercial use it is unusable, Nuki should consider that people can spin the lock, as its design encourages it. Tragedy, swapped back for a 4th generation lock because this one sucks. Have a nice day
speed
long battery life
design
unreachability (the lock does not stick properly on the attached insert)
absolutely useless for commercial use
weak lock design, often fell from the insert when unlocking/locking
go for the 4th generation if you want a solid lock that holds firmly on the insert
the yellow gears are very fragile and break easily if someone grabs the lock and wants to manually turn it
DO NOT RECOMMEND!

Quality workmanship
When the liner fits, great solution
The problem with the included insert, although it is modular, but it no longer shrinks and my old insert was 27 the first dimension and this one is 30 and it no longer fit under the fitting. The overlap was 19mm and there is no such fitting with overlap.
I returned

I've had all the Nuki locks since series 2 and with the advent of this lock I'm thrilled, the speed, battery life, looks and overall compared to previous locks it's not an evolution but a revolution just awesome. You receive the lock with the insert and a bit of patience so you install it in a while (I probably already have experience so it went quickly about 10 minutes) only thing I can complain about is the button on the lock goes stiff and sometimes I have to press twice before it responds.

Attention: The included universal cylinder is not completely universal. The cylinder comes in a 'thumb' design, and if your entry door requires a cylinder with a tooth, you won't be able to use it, and therefore the smart lock itself.
A nicely designed product.
Well designed battery charging.
Limited product compatibility.
