Just got my Red with logo. Blue w/o logo still a few weeks away.
First impressions: beautiful, solid box definitely anodized aluminum. No imperfections except for minor swirl mark around fire button. Bright display, appears as accurate as my VTR, SVR, and Provari with readings. 510 is straight. Neatly assembled inside. Screws are fine. Nice clicky buttons. Have the "two click" deal, but it appears to be the normal function I've seen on reviews- When it goes to sleep, click once, wait a second or two for the display, click again and it fires every time. I believe that is normal operation.
Otherwise, hits like a train, significantly smaller and lighter then my VTR, a real pleasure to use.
Time will tell!
