Yunzii AL66 vs RT75: your questions
Yes, the AL66 has hotswap sockets that support both 3-pin and 5-pin switches. This includes standard MX-style switches, making it easy to swap in different linear, tactile, or clicky options without soldering.
The RT75 is described as wired only according to its official specifications. While it has Bluetooth and 2.4 GHz listed in metadata, the product page states its connection is wired only. Rely on the vendor description that states wired only for gaming performance.
The AL66 has a 4600mAh battery, while the RT75 has a 4000mAh battery. The AL66 also offers Bluetooth and 2.4 GHz wireless, which can extend usage time away from a cable. The RT75 is primarily wired, so battery life matters less for its intended use.
Yes, the RT75 uses magnetic Hall Effect switches with an adjustable actuation range from 0.1 to 4.0 mm. You can set it in increments of 0.1mm per key, which is useful for tailoring sensitivity for gaming or typing.
Both use PBT keycaps, which are more durable and resistant to shine than ABS. The AL66 has Cherry profile dye-sub PBT keycaps, while the RT75 uses double-shot PBT Cherry profile keycaps with shine-through legends for RGB. Both are high quality, but the RT75 adds transparent WASD caps.
No, the AL66 is not VIA or QMK compatible. Customization is limited to onboard controls and any software provided by Yunzii. The RT75 offers web-based customization for macros and key reassignments, which may be more flexible.
The AL66 is likely quieter due to its three-layer sound dampening (Poron sandwich foam, Poron socket foam, and PET pads) and gasket mount. The RT75 also has a gasket mount and 4-layer sound padding, but its magnetic switches may produce a different sound profile.
Yes, the RT75 can be used for typing. Its adjustable actuation allows you to set a deeper actuation point to avoid accidental key presses. The gasket mount and sound padding also make it comfortable for extended typing sessions.
Yes, the AL66 includes a metal knob that can control RGB modes, brightness, or volume, depending on your settings. This adds convenience for adjusting settings without diving into software.
Yes, the RT75 supports both Windows and Mac systems, as stated in its specifications. Its web-based customization tool also works across both platforms, allowing key reassignments and macros.
The AL66 is more portable due to its 65% layout (322 mm wide) and wireless connectivity, plus a 4600mAh battery. It weighs 1145g, while the RT75 is 75% (334 mm wide) and weighs 962g. The AL66's smaller footprint and longer battery life make it better for on-the-go use.
