My first time trying a Topre keyboard after years of Cherry MX RedBrownBlue switches. I'm now using this and a Cherry Brown keyboard at work & home.
I'm definitely selling my Red and Blue keyboards, since this one is definitely much above them in regards of tactile feel and overall typing experience.
It's also my first time using a tenkeyless keyboard: definitely an improvement for typing posture.
It's very well made, the rough PBT plastic of which the keys are made of feels orgasmic.
I'm not convinced about the gray on dark gray color scheme though, the characters are mostly invisible in average room lighting. Lacking the numpad means you'll be working with the normal number keys, which are tough without seeing them.
