Seventy percent sits between a 65% and a 75%. Arrows stay, and a few extra keys come along without a full function row.
All four boards here are Keychrons. The V7 is plastic and programmable. The Q7 is the aluminum version. The K14 and K14 Pro are the low-profile wireless pair, one bare and one finished.
If you only want one, start with Keychron V7 . It is the cheapest finished board on the page, which is the right place to find out whether you want this layout.
4 keyboards
“K14, from Keychron's store”
The K14 is a 70% budget board with ABS keycaps, a plastic case with metal reinforcement and a 240-hour battery rating. Inverse called it a great starting board with a basic typing feel.
“K14 Pro, from Keychron's store”
The K14 Pro is the QMK/VIA 70% with PBT keycaps and a steel plate at about 835 g. Evidence is limited to the maker page and sibling reviews.
“Wired 70% aluminum Q with a four-pound body”
A wired 70% aluminum Q with steel plate, double gasket and QMK/VIA, about 1.8 kg. Tom's Guide gave it an Editor's Choice for build, switches and sound; it has no wireless version.
“Wired 70% with a steel plate, tray mount and no knob”
A wired 70% in ABS plastic with a steel plate and tray mount. Independent coverage is thin; Keychron's specs and sibling V-line reviews are the evidence.
