Azio IZO Numpad vs Lofree EH121: your questions
The Lofree EH121 offers more wireless options, including a 2.4 GHz radio with an included dongle, Bluetooth 5.3, and wired USB-C. The Azio IZO provides Bluetooth 5.0 and wired USB, but does not include a 2.4 GHz mode or dongle.
Yes, both the Azio IZO and Lofree EH121 are designed to function as standalone calculators in addition to being USB/Bluetooth numpads. The vendor pages for both products explicitly highlight this dual-function feature.
Yes, both numpads are hot-swappable according to their specifications. This allows you to easily remove the pre-installed mechanical switches and replace them with other compatible 3-pin or 5-pin switches without soldering.
The Azio IZO uses double-shot PBT keycaps, which the manufacturer states are designed to never fade with use. The Lofree EH121 uses keycaps made from an ABS and PC blend, which are more prone to developing a shiny surface from wear over time.
