EPOMAKER TH99: problems, parts and running costs
Checked: 2026-10-08
Summary
A compact 1800 mechanical keyboard with gasket mount, hot-swap switches and tri-mode wireless. The recurring complaints are the Windows-only Upgear software and battery figures that do not match the one independent hands-on test. There is no ongoing cost beyond the board itself, and the research treats it as strong value up to about $80 and fair at $82.99.
Common problems and fixes
- Key legends are not backlit — only the background lighting shows, so legends stay dark; there is no fix beyond changing keycaps. [3]
- Delete key sits in the top row — owners coming from a full-size board report needing to adjust; it is the layout, with no fix. [3]
- Limited accessories — no wrist rest and no dust cover, only cable, puller, manual and 2 spare switches; buy the extras yourself. [1][2][3]
- Plate-mount stabilizers — screw-in stabilizers are not compatible, which limits stabilizer mods. [1][2]
Parts and consumables
Yearly running cost
No ongoing cost: switches and keycaps are user-replaceable and there is no subscription, so a typical owner spends $0 per year on consumables. [1][2]
When it is a good buy
- EPOMAKER’s official site listed the TH99 from $82.99 (October 2026). [1][2]
- EPOMAKER’s own shop listed it at $29.05, a 65% markdown, in the same period. [5]
- German pricing ran about €79–€110 in the Smartzone review. [3]
- Thresholds: at $50 or less it is exceptional value; $51–$80 strong; $81–$100 fair; above $100 weak. [1][2]
