I bought the NS design CR4 after research on the internet, the people at Thomann allowed me to try it in the store and I was sold.
The tuning system of the CR4 is easy, it is different than an acoustic violin the strings go in the other way around. The violin does stay in-tune a lot longer , i only need to tune it every 3-4 months.
The only small bother is the neck rest, it takes sometime to find the ideal position.
When you plug in the violin I'd recommend a jack with a 90 degree angle, makes playing a lot easier.
