I like how the taste isn't super strong. I remember the first time I used mouthwash (a different brand), it was hard to swish around for the recommended thirty seconds, but I don't have any problems with this product. I've only tried the peppermint and the spearmint flavours out of the Colgate Plax range, but of the two I much prefer the spearmint, as I find it slightly subtler.
I haven't been using it enough lately to notice any real changes in my oral health, but it always makes my breath feel fresh after.
The pink bottle did state sensitive but it did feel tingle while rinsing then after spitting my teeth feel really stingy around the gum line, felt it was to harsh for me. It did leave a freshness but the sting/irritation did last a while before it ebbed away so for that I tend to stay clear of this range of mouthwashs now.
