Gateron Hippo Switches Review: Smooth Linear Contenders?
Are Gateron Hippos Worth the Hype?
Mid-range linear switches face fierce competition. At roughly $0.50 per switch, Gateron Hippos enter a crowded space between budget staples like Gateron Yellows and premium options like Durock L Series. After testing them stock and lubed in an NK65 build, I’ve identified where they shine—and where they falter.
The UHMWPE Advantage
Gateron Hippos feature a majority-UHMWPE stem, a first for the brand. This engineering-grade plastic offers lower friction than nylon or POM, promising smoother travel. In practice, stock Hippos felt noticeably smoother than typical budget linears, though not revolutionary.
Key Specs:
- 63.5g stainless steel spring (55g actuation)
- No factory lube
- 3-pin PCB mount
Lubing: The Real Transformation
Stock Hippos suffer from pronounced spring ping and a hollow, plasticky sound. Lubing is non-negotiable:
- Apply Krytox 205g0 to stem sliders (3 strokes per side)
- Lightly coat the stem legs
- Avoid over-lubing the stem hole—minimal impact on feel
Pro Tip: UHMWPE’s opacity makes lube application tricky. Work under bright light to ensure even coverage.
Post-lube, spring noise vanished, and the switches became distinctly quieter with a deeper clack. The UHMWPE advantage became clear: they rivaled Tangerines in smoothness.
Sound & Feel Showdown
Tested in an NK65 with Idabel Bluecat keycaps:
| Switch | Sound Profile | Smoothness (Lubed) | Price Point |
|---|---|---|---|
| Gateron Hippo | Low-pitched clack | ★★★★☆ | ~$0.50 |
| Tangerine | Crisp clack | ★★★★☆ | ~$0.70 |
| Gateron Yellow | Thocky | ★★★☆☆ | ~$0.20 |
| Durock L2 | Muted thock | ★★★★★ | ~$0.65 |
Hippos’ closest competitor is the Tangerine: near-identical smoothness but at a 30% discount. Versus Gateron Yellows, they’re smoother and quieter post-lube but cost 2.5× more.
The Verdict: Niche Appeal
Pros:
- Exceptional smoothness post-lube
- Unique UHMWPE stem reduces friction
- Aesthetic "hippo" colorway
Cons:
- Unusable stock due to spring ping
- No spring weight options
- Priced awkwardly between budget and premium
For builders who enjoy lubing, Hippos offer Tangerine-like performance at a better value. If you prefer stock switches, stick with Yellows or invest in Durock L Series.
Builders’ Checklist
- Lube meticulously—focus on springs and stems
- Consider spring swapping to 55g for lighter typists
- Pair with polycarbonate plates to enhance clackiness
Advanced Tool Recommendations:
- Krytox 205g0: Ideal viscosity for UHMWPE
- TX Switch Films: Tighten housing for reduced wobble (not tested)
"Lubed Hippos feel like a refined Gateron Yellow—smoother and more consistent, but not revolutionary."
