Fitted the pickup to my Lanakai tenor uke: nice balanced sound, and good output level (for a passive pickup system). Pickup comes with detailed instructions, gel glue, tape and finger sheaths for fitting under the bridge, but you'll need to drill/ream a hole for the end pin as well. It's a bit fiddly getting the pickups into the right spot (but this is true of any similar pickup design, particularly with the small sound hole on a uke). It's worth having a small mirror and a light that will fit into the sound hole, so you can see where the pickups need to go.
