Was not a quick delivery but for the price, it's decent. Accurate. We use it for getting kids to brush their teeth for 3 minutes. The suction cup sometimes loses suction unexpectedly and we find it on the floor once in a while. Aside from that, I'm satisfied.Stays up well for the first year.It's been like 2 months and this thing is still securely stuck to mirror!I have been a dental professional for 10 years. The most common issue os kids do not brush long enough. I bought these for my niece she loves to watch the sand go and finds it challenging to sit there the entire time. As simple as it is its enough to keep them brushing. I love it sticks to the mirror so its always there. And off the counter.Use this for timing making chaffles. Cute.. Ordered 3, one had broken glass.basic, cheap, it works, helps keep showers short and save water.
