HourGlass is a dual-function classroom management system that can be used as a Timer and as a Noise Detector. The giant display of lights is a dynamic measuring tool that can be seen by everyone in a classroom or even an auditorium. One year unconditional warranty. Requires 4 "C" batteries or optional AC adaptor (sold separately). Battery life in a typical classroom operation is 6 months- 2 years, but varies according to usage. Measures 15" x 8" x 4.5". TIMER MODE adds structure and focus to tests, games and other timed events. Everyone can see the lights fall from the upper part of the "sand timer" to the lower part. As "time's up" approaches the lights turn red, and a one-minute warning tone sounds. When the time is up, sound plays and lights flash to clearly signal the end. NOISE MODE helps control classroom noise. Everyone can see the rows of "sound meter" lights rise and fall, indicating the noise level in the room. At the "trigger point" set by the teacher, a warning sound plays and lights flash, signaling the room to quiet down!

Good sunscreen
I originally had purchased the spray version of this product. Unfortunately, the cans clogged so I needed to return them and I ordered this instead. It tends to go on thick but I really need heavy protection so it’s fine. Seems to give good protection and I will buy it again. I’m only giving up four stars because I would’ve preferred the spray.

Long lasting. Excellent protection.
We took a trip to Florida from DC. Through full days at Disney and days on the beach, no one had even the slightest sunburn. We made sure to apply it at regular intervals, and that seemed to work amazingly. The texture wasn’t greasy at all, and the kids seem to have no problem putting it on themselves. It was very water resistant and seemed to last long in the pool. No overtly noticeable fragrances.

One of my fave moisturizers!
Love love love this lotion! No residue, unscented and just enjoyable to use. It is very hydrating and great to use after you've been outside or just need a little extra boost to your skin. The ingredients are exceptional and I'm really excited to try other Blue Lizard brand products!! Try it, I don't think you'll be disappointed!
