Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Great Water Bottle!
Color: Off Road, Size: 30 Ounces
I was looking for an insulated water bottle that would actually fit in a standard cup holder. I decided to try the Owala FreeSip Sway Insulated Stainless Steel Water Bottle. Upon receiving it, I noticed that it felt solid in my hand. The mechanism worked very smoothly with a simple button press opening the lid. Once open, you can choose to either use the included straw or tip the bottle and drink from the chug spout. In addition to it fitting in my cup holder, I needed it to be leak proof. This bottle is leak proof, and the spout can be locked by engaging a lock in the back. The rugged flip handle is also a convenient way to carry the Owala when it's not in the water bottle holder on my backpack. I hand wash the body of the bottle, but the top disassembles easily and can go right in the dishwasher when I want a deep cleaning. The bottle has a wide opening, so it is very easy to clean the inside. This has quickly become my favorite water bottle due to its ease of cleaning, good insulation, ability to fit in my cup holder, solid construction and materials, and the option of using the straw or chug spout. I have the 30 ounce bottle, but I am going to be picking up a 40 ouncer also. You won't regret purchasing one! I have used the bottle for a couple of weeks now, and here are my observations: It has gone on two camping trips, and it has proven to be durable. I have placed the Owala on its side on my passenger seat (just to test it...it fits perfectly in my car's cup holder!). It did not leak a single drop on a long road trip. On my camping trip, the water in the bottle was still ice cold the next morning, so it keeps cold beverages very cold!

The Perfect Bottle
Color: Dreamy Field, Size: 40 Ounces
I do not leave reviews, but I had to for this. This is the PERFECT water bottle. It has a handle, it's leak-proof, with a lock, so you don't have to worry when your baby decides to play with the bottle and tips it over -- there won't be a spill! Straw and sip option are perfect and I love that the straw is inside the cup so I don't have to worry about my kids hurting themselves when they drink from the cup. 40 oz is a great size, holds a lot of water but tapered bottom perfectly fits in the cup holder. So easy to use, my 4 year old has no issues. Cleaning takes 3 minutes. I recommend to absolutely everyone.

Great quality, beautiful colors!
Color: Black Cherry, Size: 30 Ounces, Color: Black Cherry, Size: 30 Ounces
I love my Owala! The colors are beautiful. It's easy to wash out and clean. I like the lock function. There's been a couple of times that I've put it in my purse without locking it and the button accidentally pressed open and spilled. So the lock fuction definitely comes in handy! It's easy to carry around with the handle. It doesn't feel overly big/bulky. It fits in my van cup holder just fine. My toddlers are able to drink from it using the straw function without spilling and making a mess. If I put a lot of ice in it, it usually still has ice the next day. It stays cold for quite some time. The overall quality is great! I'm pretty rough on it and it has minimal scratches so far. I definitely plan on buying more colors in this size!

Amazing, but gigantic. Gave to my partner.
Color: Summer Sweetness, Size: 40 Ounces
5 stars because I got this bottle on sale for the same price as the 30oz, the colors are *gorgeous* and every bit as vibrant as the image shows (which I'm seeing is not typical across the board for owala) and it is indeed just a fabulous, strong water bottle. Easy to drink from the built-in straw, a joy to carry, and fits in every cup holder so far. I've already adapted better hydrating habits compared to using my old daily Nalgene. However, I am 5'5 and wanted a bottle to carry around frequently for work. This thing is like as big as my thigh bone lol! I should have gone to a local Target or Academy to compare the 30oz vs the 40oz bottle because the size difference is significant. If you consider the added weight for a full 40oz, I set myself up for failure in terms of my needs for this bottle. My 6'2" boyfriend who loves colors and works outside all day was happy to adopt this one for me however, and I ended up purchasing a 30oz elsewhere in equally fun colors. We have both had success having ice last a full workday. His keeps cold in the car and mine usually has a good bit of ice still after 3 refills and constant use. So far so good on no-spills, and I really appreciate the lock mechanism as I work around delicate artwork all day. It would be nice if the cups were machine washable alongside the gaskets, lid, and straw-- but alas, it's easy enough to clean in the sink and probably wouldn't fit in a top rack anyway. Each bottle comes wrapped with beautifully thorough care and use instructions as well-- take the time to read it all! Overall, I would recommend this cup 10/10. Cold water all day and a built in straw have changed my daily water intake by and large-- so if you're looking to better your hydration habits, look no further and don't overstep your needs like I did if you work around available water spouts all day... The 30oz is enough.
