Better than 400cc and 250cc, because the height of the tall is low, in the bottom of the locker of the car, in the engine room, it is very easy to handle! Because the lid has a spherical shape, it closes even if it is placed diagonally and does not spill liquid. Although there is liking, up to free angle (personal) is not necessary. I think the price is cheap and good thing.
I usually use 250 ml cup, but I made it to this cup one size smaller as it gets in the way when blowing a narrow place. It was not a free-angle type so that it could be easily replaced at the work site, it was made into an ordinary screw type cup. It is good to be able to adjust the length of the feet (screw), but it was even better if it got longer a little longer.
