Fine product with ok price/quality. But no attachments for hoses included nor screws for panel attachment. Missed chance for 5 star rating

After 10 hours it is now off. When I was flying the last time I noticed that my Steam Gauge Air speed indicator was reading faster than my Dynon Skyview. It was turbulent and the needle was bouncing around. so I couldnt tell by how much but it looked off. Yesterday I went out and got my syringe and tested the Pitot Static system. The System Looks good, no leaks, but sure enough the Steam Gauge is showing 20 mph faster than the dynon. So what happened in the last 10 hours of my phase 1 testing? Should I send the Steam Gauge back? just ignore it? I really like glancing at the analog gauge on final and takeoff. Now I know that on the madden flight the steam gauge was very close to the dynon, I have a picture from the first flight where the Dynon indicates 88, true is 93 ground speed is 99 and the steam gauge is reading 92.
