Glad I bought these because there are so many colours available

Note: I did not use the band included in the product and instead used a rubber band.Bought these for a lighting experiment for my color class (paint a mask and see how different lights affect the color) and they don't disappoint! First image is regular fluorescent lighting, the three intense ones are dark room + only light is from the flash, and the light pink one is next to an open window during the day + flash. Product was easy to use and comes with a convenient case so you don't ruin the filters too.

This sound machine is extremely user-friendly and intuitive to use - even when you're half-asleep and about to fall into bed. SO happily simple that the only thing to "figure out" is which sounds are your favorites!The volume on this machine goes quite high (at least twice as high as I could ever imagine needing it to be.) The entire top surface of the machine appears to be a speaker panel.If you don't want the setting buttons to glow and prefer that the face of the machine be completely dark all you have to do is press the "display" button which turns those lights on and off.The timer button gives you the options of setting the machine to play for 30, 60, 90 or 120 minutes, but if you don't set it on any of these it will play endlessly or until you turn it off.The sound options are as follows: waterfall, fireplace, ocean, meadow, train, city, rainfall, brook, meditation or white noise.As someone who's particularly fond of nature sounds, I have to comment that I was surprised how much I liked the "train" option when I gave it a try. It sounds just like you're riding on a train and it's gliding over the tracks, which lulled me right off.The best thing about this machine is that (unlike the other sound machine I own) you don't feel like you're listening to the same thing again and again on endless, annoying loop.As just one example, for instance, the "WAVES" option combines the rising and falling of waves with the occasional sweet bleating of a seal, the soft toot of a tugboat horn, the deep, faded toll of a lighthouse fog bell, a few very distant chirps of some seagulls and so forth. The user manual calls these interesting noises that punctuate the main sound (in this case the main sound would be the "waves") "stories." The "stories" are adjustable. Set the "Richness Level" on "Low" for only the waves. Set on "Medium" to add other sounds. Set on High to add still more sounds to go along with your ocean waves. Everything comes together in a realistic mix: for instance, sometimes the seal bleats once – other times more than once. These sounds interspersing the waves come only occasionally and just often enough to make the "scene" you are hearing seem very realistic – not to mention extremely relaxing. Even the waves themselves aren't monotonous – sometimes they'll roll in a loud rush several times and then quiet down just like a real ocean does. There is also an "Adaptive Mode" function that will adjust the volume to drown out noises from other, outside sources turning the volume a bit louder when there is an intrusive sound of some sort that might threaten to wake you up. This is an option you can turn on or off easily depending on your own preference. Again, all of this customizing is extremely simply and easy.In short, I am very happy I bought this sound machine and couldn't be more pleased with my purchase. I only wish this company would make a small version of this machine for use when traveling.

I use this product in my practice every day. It is a great addition for my work space as I operate in busy business center near a train station and the machine help to mask some of the associated noise. This makes my work space quite a comfortable place to work for my and my clients.

perfect and easy to use! I use it for gigging and performing live. You can find some of my recordings with this products on my accounts here:Instagram: Froylan.kiddFacebook: /Froylan.kiddYouTube: Froylan Kidd

we don't know much about these things but it was very easy to use and we saved all our pictures and documents

This was so easy to set up and use. Will come in handy!!

I like the convenience of not having to provide keys for my dog sitter, neighbor and house cleaner. I haven’t had that long to know how long the battery lasts. I like the automatic lockout after password has been put in more than 5 times. I really like the money back guarantee and warranty that it carries. It was easy to install, the provided video walked through the install process to make it really simple. The TTlock app is easy to use and easy to assign temporary or permanent access codes for entry. This does support wifi BUT you will need to purchase a gateway in order to be able to use with Google or Alexa. This is my first smart lock and so far I like it. Another feature I like, if the batteries dies, I can use a 9v battery to gain entry. Overall, convenient and easy to use.
