great water bottle, doesn't leak
Color: Camo Cool, Size: 24 Ounces
Headline: Finally, a Water Bottle That Lives Up to the Hype!⭐⭐⭐⭐⭐"I’ve tried almost every popular water bottle brand out there, and the Owala FreeSip is genuinely in a league of its own. The 2-in-1 spout is a game-changer—I love being able to sip upright through the straw or tilt it back to chug. It makes drinking water so much easier.It’s completely leakproof when locked, which I’ve tested in my gym bag multiple times. Plus, the cover keeps the mouthpiece sanitary. It keeps my water ice-cold for over 24 hours, even sitting in a hot car. And let's talk about the colors—they are so fun and vibrant. I got the 24oz, and it fits perfectly in my cup holder. If you’re on the fence, just buy it!"

Great Water Bottle but failed after one year.
Color: Foggy Tide, Size: 32 Ounces
I purchased this Owala water bottle a little over a year ago and it was in my top favorites. The flip-up lid is a great feature, and I like that you can use it with or without the straw. It’s completely leak-proof, comfortable to carry, and has held up well with daily use. My only complaint had been that it doesn’t fit in most standard cup holders. But after about a year, I did notice that it stopped keeping my water cold as long as it used to, and the ice began melting much faster. I reached out to Owala customer service but unfortunately never received a response. Even with that issue, I still prefer the lid design over brands like Yeti or RTIC, so I would consider purchasing another Owala in the future. If you value a convenient, leak-proof lid design, it’s definitely worth considering. I just sincerely hope the insulation lasts longer on the next one.

The BEST water bottle on the market!
Color: Denim, Size: 32 Ounces
I am in love with this water bottle! I take it everywhere with me, and I love that it has a built-in straw. The color is perfect as well. It motivates me to get my water intake in, and it helps me meet my fitness goals. It is easily washed in the dishwasher, and I don't have to worry about it breaking. It keeps the temperature of my water perfect- whether I add ice or not. It is sturdy but not too heavy.

Excellent Summer Resource for Kids!
Format: Paperback
I purchased the "Summer Bridge Activities 2nd to 3rd Grade Workbook" for my 8-year-old, and it has exceeded my expectations in every way. This comprehensive workbook is a fantastic tool to keep children engaged and learning during the summer break. My sibling is an elementary school teacher and introduced me to these books when my son was in Kindergarten and I honestly have not looked back. My LO loved a good challenge so we typically do multiple days to ensure we finish it in its entirety during the summer. I'm constantly recommending these books every summer as I have not yet found anything to replace it. Content Quality: The workbook covers all essential subjects: math, reading comprehension, writing, science, social studies, and even fitness. Each section is well-organized and filled with age-appropriate activities that challenge and entertain. The variety of exercises ensures that my child doesn't get bored, and the progressive difficulty helps build confidence. Educational Value: The math and reading comprehension sections are particularly strong, with clear explanations and plenty of practice problems. The writing prompts encourage creativity and critical thinking, while the science and social studies sections introduce interesting facts and concepts. I appreciate the inclusion of fitness activities, promoting a healthy lifestyle alongside academic learning. Flash Cards: The included flash cards are a wonderful bonus. They are durable, colorful, and perfect for quick review sessions. My child enjoys using them, and they make reinforcing concepts fun and interactive. Ease of Use: The workbook is user-friendly with clear instructions for both parents and kids. It's designed to be self-paced, which means my child can work independently or with minimal guidance. The answer key at the back is helpful for quick checks. Engagement: What sets this workbook apart is its ability to make learning enjoyable. The activities are engaging, and the themes are relevant and interesting. My child looks forward to workbook time each day, which is a huge win for any parent trying to prevent the summer slide. Overall, the "Summer Bridge Activities 2nd to 3rd Grade Workbook" is an excellent investment in your child's education. It's thorough, fun, and well-designed to keep young minds sharp over the summer. I highly recommend it to any parent looking to provide a balanced and enriching educational experience during the school break.

Good quality for price
Format: Paperback
This was a good book for the summer. It has a variety of activities so my child didn't get bored. It also has some fun "outside" only ideas to get them up and moving. It was a good bridge book that she could (mostly) do independently. However, as they progress through it, parents should be there to help and reiterate different concepts. It was well worth the price and helped the transition go smoothly.
