Thank you so much for your wonderful response and interest in how I use your product. I am delighted to answer your questions.
First a little about myself, and the racing hobby. My start began in local scouting where I would participate in pinewood derby car racing, which involved building a car, cantering the wheels correctly,
adding weight, and finally making lots of practice runs to add lubrication evenly and increase the car's speed on a downward ramp style race track using gravity.
I did this through my teens and then continued with my own children and have several pinewood cars that did very well.

Currently I broke into the diecast 1:64 hobby because I could do speed modifications to 1:64 cars and create more fast cars for the track. I presently have a 6 lane 9ft track with a timer, and a 15ft(+) ralley track. My modifications involve changing wheels to ones that work better on either track, believe me I have certain wheels that perform better on ralley and others that work best on the 6 lane drag. In addition, I add weight, polish, cut, and tub out wheels where needed for speed.
Where your product has become a must is in work bench dynoing the cars at the different stages:
Stage 1: Car in the raw after wheel swap to make sure wheels
are aligned and car is not jumping around.
Stage 2: Car with weight or tubbing with the same test as
above.
Stage 3: Car after each stage of lubrication I use for the same
above, increase speed and to gain less wheel noise.
Cars that I screen out, I either donate to a local food pantry, or offer to other racers to see if they can increase the speeds.
After I build my racers or find one that I am using, I will use the runsible to warm the car up before the races. The reason for the condition you see in the photos is that a warm up is typically 30
seconds and I can be warming up over 50 cars at a time. Also the clear rubber peice in the photo is a "glob" of hot glue that keeps the cars from moving off to the side on the side that is not visible to me
on the work bench, so I know all the wheels are warming at the same
time.
To answer the season use, I use the runsible all year and average two nights a week for at least 2 hours or more per week. I did learn (because I probably did not read), that you can run it on usb instead of batteries. This was important because in my first use some how new batteries leaked and cause the battery compartment to corrode like you see in the photos, so you make want to strengthen the usb message with a sticker on the battery compartment and add that it should not be
stored with batteries in it.
I presently enter mail in diecast races and online races through "whatnot" or other social sites.
Thank you so much for the complimentary runspin, as you know I will use it. I am more that willing to participate in your second suggestion of sharing with others, just let me know how I can help.
Finally I have attached a video of my work area, hope it helps..
