This is an un-managed switch with 4 2.5Gb Ethernet ports, and 2 10Gb SFP+ ports. Sold by Sodola networks. I went ahead and bought it as it was on sale for only $38 and lists a 1 year warranty. It gets decent reviews overall, and there are managed versions, but one of the main complaints about these are that if you need to manage your switch, the management available isn't very good.
