Okay !  Dislike the "plastic" taste! [SEP] It's okay, but I'm not loving this water flosser and would not buy it again or recommend it.<br /><br /> Main reason -- Even after rinsing the &#34;tank&#34; several times before use, it makes the water have a &#34;terrible&#34; plastic taste.  I did resolve this a bit by adding some of mouthwash to each tank of water before I use it, however I can not use it without adding the mouthwash because it makes the water taste terrible and did want to be able to use it with only plain water.<br /><br /> Secondly, it is rechargeable, but only via a USB connection, not a standard &#34;home&#34; electrical out as I had I expected (NOTE:  It says it's 120/240V compatible) which is why I thought it would be charged via a standard electrical outlet versus a USB Port.  USB is okay for those who own computers, (I do), but we certainly don't keep our computer in the bathroom.  I have to charge it in my office, which is a bit inconvenient for a bathroom product.<br /><br />On the upside, it does work pretty well, once you can get used the the water taste and it's nice that the are three settings.  However, I feel the tank is too small and need to refill it for each use.  One full tank is not enough to clean all my teeth, even on the &#34;pulse&#34; setting.<br /><br />Overall, it's okay and does serve the purpose, but would be MUCH better if it did not make the water have the awful &#34;plastic&#34; taste and if the take was larger.  If I could have returned it for a full refund I would have.  But, since it's NOT defective and there is not a free trial period, I'm stuck with it.  I'm going to use it for the time being and continue to look for a better product.
