All guides →ABS vs PBT Keycaps, How to Pick Your First Set
ABS, Acrylonitrile Butadiene Styrene, is smooth, glossy, and cheap to injection-mold, which is why almost every stock keyboard ships with it, but it absorbs skin oil and turns greasy and shiny within months of daily use. PBT, Polybutylene Terephthalate, has a higher melting point and denser structure, so it comes out matte and slightly textured and holds that finish for years. That one material difference drives feel, sound, color stability, and price. A first custom keycap set is less about finding the perfect material and more about not overspending before you even know which profile you like.
Read guideDecoding microSD Card Speed Classes Before Your First Buy
A microSD card can carry four separate rating systems stacked as tiny icons, Speed Class, UHS Speed Class, Video Speed Class, and Application Performance Class, and most listings never explain what any of them mean. U3 guarantees 30 MB/s sustained writes, V30 guarantees the same thing under a newer name built for video, and A2 measures something else entirely, random-access speed that only pays off on a handful of supporting devices. Once you know which icon answers which question, picking a card stops being a guess.
Read guideDo You Need a Thunderbolt Dock, or Will a USB-C Hub Do
A docking station is only worth the price jump if your laptop can use what it offers. Plain USB-C hubs cover basic charging and one or two lower-resolution displays for around $30 to $50. Thunderbolt docks add real bandwidth, up to 40 Gbps on Thunderbolt 4 and up to 120 Gbps on Thunderbolt 5, plus up to 240W of charging and dual 4K60Hz displays, but only if your laptop's port actually supports Thunderbolt. DisplayLink docks split the difference, driving multiple monitors from any USB-C port through software instead of native video-out. Match the dock to your port and your charging wattage first, then shop by price tier.
