Grove - 0.54‘’ Red Quad Alphanumeric DisplayThis module is a 4 digit alphanumeric display with high brightness and red backlight, each digit is consists of a 14 segment digital tube. The commonly used 7 segment display, such as our Grove 4 Digit Display can only display the numbers 0 9 and a limited number of letters. In contrast, the 14 segment digital display does not have this limitation, it can display all the characters, that's why we call it alphanumeric display. Usually, the 14 segment
This module is a 4 digit alphanumeric display with high brightness and red backlight, each digit is consists of a 14-segment digital tube. The commonly used 7-segment display, such as our Grove - 4-Digit Display can only display the numbers 0-9 and a limited number of letters. In contrast, the 14-segment digital display does not have this limitation, it can display all the characters, that's why we call it alphanumeric display.
Usually, the 14-segment display needs to use 17 or more wires to control the display, which means that a large amount of IO of your main control board (such as Arduino) will be occupied. With the help of on-board HT16K33 chip and Grove connector, we made it an i2c display, only four wires are enough. No troublesome soldering and no complicated wiring

Nice Frames
Color: Black, Size: 8x10
I purchased two of these frames in black. I was pleasantly surprised at how nice they are given the price was so low. I removed the film on both sides of the plexiglass as instructed and it was crystal clear. These are not high quality frames if that's what you are looking for.....real wood or glass. However, they are awesome for the price and what I needed them for. I would purchase them again.

I got this to hang a photo in my office and it was perfect for my needs. It was very easy to open the back and install the photo and the enclose back up. It is very well made and it looks great. It hangs nice and neatly on my wall and is great for displaying my 8x10 photo I needed to show off.

The ultimate water bottle
Color: Iced Breeze, Size: 24 Ounces
I can’t believe I’m so excited about a water bottle. The design is amazing - I love that there’s no straw poking up but there’s still a straw sip function. I like that the carrying hook doubles as a lid locking mechanism. This bottle feels very sturdy but it’s sleek and easy to grab - I have small hands and it isn’t a problem for me to drink from with one hand. It’s also really nice that this bottle fits in standard couple holders both at the gym in the machines and in my car. The color selection is so fun and I am pleased that my bottle looks exactly as pictured. My water has stayed cold and my ice cubes frozen for over 12 hours now. Cannot recommend enough!

Keeps drinks cold all day
Color: Very, Very Dark, Size: 24 Ounces
We got this Owala bottle for our son to use as his everyday school water bottle, and it has been excellent. The 24oz size holds plenty of water for the school day without being overly bulky or heavy to carry around.
The insulation works extremely well. Drinks stay cold all day long, even when the bottle sits in a backpack for hours. That’s probably the feature we’ve been most impressed with so far. It’s also been great for car trips since it keeps water cold for extended periods without needing constant refills.
The design is really well thought out too. The built-in straw makes it easy to drink from quickly during class or while traveling, and the lid feels secure and leak-resistant when closed. It also has a clean, modern look that feels a little more premium than many standard water bottles.
Build quality feels solid overall, and it seems designed to hold up well to everyday use from school, sports, and travel.
Overall, this has been a fantastic everyday water bottle and definitely lives up to the hype. Keeps drinks cold, holds a good amount of water, and works equally well for school or road trips.

Cup holder friendly AND functional!
Color: Denim, Size: 24 Ounces, Color: Denim, Size: 24 Ounces
I have a dupe of this cup in a 32oz version and I’m in love with it except for one thing, it doesn’t fit in the cup holders of my vehicles very well. For Father’s Day, my husband needed an insulated cup for when he works outside, his current one doesn’t fit in a cup holder. This was a perfect option for him since he likes the one I have. First things first: this thing keeps liquids COLD for a VERY long time. Haven’t put anything hot into it and don’t plan to so I cannot attest to that. It’s lightweight, durable, and the versatility with the straw is really what makes this cup stand out. You can use a straw OR take a sip without changing adaptors or adding a straw. The straw is basically built into the spout. It’s leakproof which I greatly appreciate. With this being on sale I jumped on it. These are such nice cups, and I can confirm they fit the cup holders of my vehicles from my 22 RAV4 to my 05 Corolla. This is a definite buy and I really hope my husband gets me one since my dupe doesn’t fit in my cup holders. As for the 24oz of this cup, it fits. The colors are fun. It’s unique, and extremely functional.
