Redragon S101M-KS: problems, parts and running costs

Checked: 2026-10-08

Summary

The headline caveat is the switch type: this is a “mechanical feel” membrane keyboard, not a mechanical one, despite the category it sells under. The most reported annoyances are quick sleep with a wake delay, a mouse that needs frequent recharging, and settings that do not save between sessions, with two Reddit owners reporting wireless failures. Running costs are charging only, and the bundle is a fair buy at about $50 when you want a full-size tri-mode keyboard and mouse on a single receiver.

Common problems and fixes

Keyboard unresponsive wirelessly — two exact-model Reddit threads: one owner’s keyboard went unresponsive with the “M” light blinking, and another’s powered on but only worked when plugged in over USB. Owners attempted re-pairing and FN+1/2/3/4 and FN+Esc resets; these are individual reports, not a failure rate. [19][20]
It is a membrane keyboard, not mechanical — Redragon’s own copy calls it a “mechanical feel membrane keyboard” and a third-party round-up lists it as membrane, while the listing sits under mechanical keyboards. No fix: buy it for what it is. [1][7]
Warranty conflict — the Redragon product page states 1 year, while the shop download pages state a 2-year limited warranty. Confirm the term on the specific order page. [1][3][4]

Parts and consumables

No other replaceable parts or consumables are reported: no parts catalog exists, and the keyboard and mouse are programmed with two separate utilities. [2]

Yearly running cost

There are no consumables and nothing scheduled for replacement, so the only running cost is electricity for charging. The 4000 mAh battery is rated up to 300 hours with RGB off, against about a week of regular use with lighting on and several days for the mouse, so an owner who leaves the lighting on charges weekly while an owner who turns it off charges rarely. The research contains no charge current or electricity rate, so there is no dollar total to publish; estimate it as the pack capacity times the number of charges a year times your local rate per kWh.

When it is a good buy

$49.99-54.99 at Redragon (October 2026): the normal buy zone. The $54.99 list drops to $49.99 with an auto-applied code; the single receiver for both devices and the 300-hour keyboard battery are the real differentiators at this price. [1][7]
Above $60: weak. At that money it competes with entry-level mechanical keyboards and better-documented wireless combos. [7]

Alternatives:

Redragon S101P-KS — the sibling wireless combo, also $44.99 at Best Buy (October 2026). Same idea in a different model; compare the two spec sheets before choosing, since they are not the same board. [8][22]
Redragon S101-4 wired combo — $44.99 list at Redragon (October 2026). The better choice if you want a wired combo and do not need tri-mode wireless. [23]
