It sells for about $50 (£29). In practice the thumb‑rest feels solid, but the side buttons are inconsistent, the clutch wheel is stiff, and the bottom skates feel rough.\n\nFor users who need an ergonomic form factor on a tight budget, the EM25 offers the basics without the premium polish. However, anyone accustomed to the smooth glide and reliable controls of a true MX Master will notice the downgrade, making the mouse a compromise rather than a true substitute.\n\nIn short, it’s a decent placeholder if you must stay under $50, but expect to trade comfort for cost.","[\"ergonomic-mouse\",\"hardware\",\"review\"]","2026-06-12T16:31:51.000Z","2026-06-12T17:17:24.157Z","2026-06-12T17:17:31.017Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Fprotoarc-em25-ergonomic-mouse-falls-short-of-logitechs-mx-master.webp",[26,27,28],"ergonomic-mouse","hardware","review",[30],{"name":31,"url":32},"PCGamer","https:\u002F\u002Fwww.pcgamer.com\u002Fhardware\u002Fgaming-mice\u002Fprotoarc-em25-ergonomic-mouse-review\u002F",0]
