VAYDEER appears once on this site, in wrist rests and mousepads, with its STK011 keyboard stand.
A stand, not just a rest. The ELZO and LogiLink are wrist rests and the Hama a mouse pad; the VAYDEER raises the keyboard itself, with an elastic memory-foam front edge for the wrists, in one seamless piece. A rubber base holds it in place, and the smooth surface resists dust and wipes clean, with no seam between stand and rest to trap dirt.
But no heights. The listing gives no dimensions — not the width of keyboard it takes, how high it lifts it, nor the height of the rest. For a product whose purpose is to set heights, that is the question to put to the seller, or to answer with a ruler on arrival. Only the Hama in the hub publishes a rest height, 2.1 cm. A raised keyboard also changes where your elbows should sit — should your elbows be supported while typing? covers it.
A claim we do not repeat. VAYDEER says the design helps prevent neck, shoulder and back pain; this site does not repeat that as a health claim.
The price. About $22 on Amazon.com when we checked — less than the Hama ($24) and LogiLink ($35), more than the ELZO ($8).
