The price is the same as other cheap BiDi SFPs. However, these only work with Unifi/Ubiquity hardware, while the others I've used from 10Gtek work with everything. Since you need the right pair of these, unless the other side is Unifi/Ubiquity, this quickly becomes a showstopper. For this reason I'm giving it a low score as it's a common case that goes unaddressed at all and lets many down.
