Id give it a 4.5 star only because the holes weren't well rounded on the interior were they punch through the mold to make the holes. Other than that I tested if it holds full of water and all seals work. The fix: grab a knife scrap the inside ring and it will fall off. If you want a more perfect feel (not rough) heat up a flat head or screwdriver that has a round stem and use that after heating to lightly melt the plastic to smoothen it out. I didnt do 2nd part dont care. Great size, will fit under motorcycles easily like my 04 zx10r.
