A nice but honest review from the Retro Shack of the 48K+ ZXuitape which is an SD solution for a ZX Spectrum. If you need a solution that lets you load games into your ZX Spectrum 48K+ from an SD card this is the one. It screws into the speccy case to make it look like part of the speccy. ZXuitape comes in different models. This is the model for the ZX Spectrum 48K+. You can use it to load up games in tzx, p, o, or tap file format.
