Very sensitive touches: for a targeted audience
Speed Silver switches are for those who expect extreme sensitivity (for certain types of games, it seems). Because the activation distance is so short, touching them can cause the keys to activate. This can lead to frequent typing errors with adjacent keys (annoying when typing text). Unfortunately, LDLC's current alternative for this model is Blue switches (which are much less sensitive but very noisy).
In terms of noise, this is still reasonable, but more than Silent Red, and it could still annoy the other people present.
So for these two aspects, I'd advise either getting another model with the switches you'd expect, or changing them (with 80+ keys, that's going to be a budget).
Like other mechanicals, the keyboard is quite high: 3cm for the front keys, 4cm for the rear ones. I think it's essential to have a wrist rest (1.5-2cm seems about right). Keyboard width: 33cm.
I find the placement of the start/end/page up/down keys impractical (perhaps over time...).
The keyboard is programmable with VIA/QMK: the keys can be reassigned via Google Chrome. I was thus able to add a combination to switch from PC to Mac mode (inversion of the win-alt-left keys) and others for the media keys (volume, playback), which compensates for the compact size.
As for the backlighting, there are several animations to choose from using a keyboard shortcut, and the speed is configurable. I didn't want it, but in the end it's fun and relaxing. The keys are opaque black (unlike others with transparent lettering).
Key and switch extractors included, connects with USB-C to USB-A cable supplied.
Made in Taiwan (the only non-Chinese manufacturer I could find).
