Good field screwdriver kit – XIAOMI Mijia Wiha
Xiaomi Mijia Wiha is a quite decent screwdriver kit. A nice slick case, good handle, decent bits. The only problem I have with it is lack of H2.5 and H3 bits in a default kit. Luckily, additional bits can be purchased separately under the name Xiaomi Wowstick Bit Set. Set X1 has both H2.5 and H3, so you can make your own set.
