"Excellent product for keeping TTL information"
Pros
Small, long range, ease of use

only two channels (but you can configure 30 channels on either one of the config channels)
no auto shut off (will wear your battery down if you forget to turn it off)
Need TT1 or an additional TT5 to fire your flash
