I went to the Geekworm site looking for a pi4-SSD adapter to take advantage of the (at long last) ability to boot a pi4 from SSD.
The site is well worth a visit, as there is a lot of tasty kit, ranging from an integrated UPS, through M2 adapters to the mundane SSD adapter I sought and more. Well worth a browse if you feel like spending lock down periods making better use of your Pi.
