I use Deck 87 Francium Pro - White Backlight - Cherry MX Brown
Brown switches are one of oldest.
I think only Black are older but I hear them and always I had impression like noise of some cheap plastic.
Blue are for typing and people who like strong clicky sound. Red are for gamers but almost you have no feeling or mechanical keyboard. Brown are 50% for typing, 50% for gaming. You hear nice click but not as Blue.
Green, White and Clear I'm not sure ...
I'm very happy because In last moment I changed from Hassium PRO to TKL version looking all nice small keyboards.
I don't know why people from USA territory very rear decide to buy Deck keyboard... All RGB keyboards if something happen with software... What you have... Keyboard where main advantage is thousands colors is not keyboard. Keyboards need to be excellent and without lights completely and LED light only to be small positive things not main purpose.
Before that I had Logitech G510 and I still think she is one of best non mechanical keyboard and one of nicest non mechanical keyboard. G510 served me 5 years and it's really not usable any more.
I import my keyboard from USA only to have Double Shot PBT switches... and ask first on mechanicalkeyboards for version they have.... I didn't want keyboard as on pictures below...
This is Francium Pro from some Asian site and I didn't want that type... even some of them are with orange LEDs...
Look difference between fonts and shine ABS keys...
Many people sell on E-Bay and if someone want to buy from Europe better to order from mechanical keyboards...
You see now if you want Deck Francium Pro PBT should be as on first picture, it's easy to recognize with big CTRL WIN ALT.
Someone don't like that fonts but I didn't saw nicer anywhere, I like them.
