Quanity
Very easy to work with and plenty of “ how to” videos to help with sprinter. Only complaint is the quantity recommended. The boxes are huge and 3 boxes were advised by Havelocks chart. I used only 2-3 bats from 3rd box. Smaller boxes would be great. Shipping is bery expensive on the large boxes as well. Haven’t really put it through a test hot or cold but like so far.
