I should say it's nice and does the job. The only problem is the green liquid goes clear because of it being in the sun all the time I wish there was something they can do to keep the color. I would have given it 5 stars but because it goes clear. It's still useable but the color does help. I think I would still recommend this even with color loss but the bubble still can be used.
