i just added a 2-star one although i'm unsure why i rated it that high. the blue color was nice and the texture is grippy and that's the only good thing i can say about it.
i just put in for a return and ordered this sleeve until 3rd parties take up the slack. hope the sleeve fits, the oasis is a tricky size:
