strong chemical smell and taste [SEP] i really wanted to like this i got it to replace my old one which finally stopped working the buttons on this one are too close making it hard to control and it is hard to fully drain the reservoir but mostly it has a strong chemical plastic smell and taste that has not faded at all with use i ve tried everything even putting mouthwash in the reservoir but it s still an overpowering chemical smell and taste i cannot recommend this
