New 20 ounce tumblers available now! Forum donation credit with purchase. https://www.wildguzzi.com/Products/products.htm#Tumbler
I have one that I keep under the seat. Very well made but nothing works as well as a pair of multi grips.
Nah the grips will f'up the stick over time. This works perfectly though I find tapping the end of the tool once lightly with a rubber mallet is the best way for me to break it loose.
That's nice. Wish I had one before I ruined the dipstick with the channel locks..
