Great - while they work
These Denplugs are great for suppressing the high pitched sounds of high speed handpieces and high volume suction in the office, but they do not last nearly long enough for the price. I bought 2 pairs out of necessity, but the two pieces that make up each earplug separate after only a few uses and do not reconnect. They are meant to be a two-piece design, but once the blue plastic plug works its way out of the silicone portion, it does not stay reinserted because the plastic surface is too slick for the silicone to grab on to it. Both pairs I bought are now worthless and they are not worth the cost.
