Well made, high quality instrument. Mine is mounted high on the panel in the center its always in easy sight, used as a seat-of-the-pants check instrument. Good damping in turbulence. This is installed in a variation of a Super Cub with no gyros and gets a lot of rough use no problems noted in about 300 hours.

Got what I wanted. 4 stars because order languished in Wasilla for a while until prodded by Spruce in CA to ship it.

Looked great when it came in, little heavy. But it sat a few months before I installed, when I got around to installing, it had leaked the fluid out about half empty. Not functional now.

Unit works fine on ground, does not work in plane, it stays at 0 all the time no matter how steep of bank I do. I fly a J3-Cub
