Definitely a AAA Company! [SEP] This company h2ofloss it's probably the best in this type of business! I have helping every aspect. And when I had a problem that corrected it. The portable is probably the best for my use because it's use 5 months out of the year at one house I'm not used again. I will empty the container before I leave here and I know it will work well when I come back. Well worth the money and certainly well worth having this tool to help clean my teeth!
