So first, this cup is an awesome alt to name brand. Keeps water super cold for respectable amount of time, dishwasher safe, and almost 100% spill proof. There is a rubber seal around the straw that allows just the amount of water inside the straw to come out when completely flipped over. The lid is also very spill proof and sealed with a rubber ring- it pushes on, does not screw in. I have a horrible habit of knocking my cup over and this was exactly what I needed. It's also 40oz (bonus points for fitting in my car cup holder) so it's an upgrade from my "mythical arctic creature" tumbler.

That being said, after about 5 months of knocking this cup off of tables the straw finally snapped in half. Other tumbler straws do work, but I went to the company's site and emailed them a photo and asked if it was possible to get a replacement straw and they sent it in about 3 days. That customer service is the reason for this review. Love being able to not have to buy a whole new cup and add waste to a landfill for an easy fix.

Worth a note with how rough i am on this cup that the outside is not scratched or dented in anyplace and doesn't have dishwasher heat discoloration like some of my other cups.

Negatives first, when you press the lid in with liquid in the cup, it will squirt out of the straw. I place a finger over the straw hole and press the lid in. Second, the cup is slightly too top-heavy when full. I've never had it tip over, because I was able to catch it. Also, on mine, the rubber base isn't set flat so the cup has a slight lean to it. I just need to always be mindful so it doesn't tip with the slightest nudge. Third, I have been using this for several months and the handle now has a very small amount of movement. My concern is that it may continue to get worse. Fourth, the straw is rigid, which I prefer, but the downside is that it makes a pretty good seal when pressed all the way down. I fixed this by cutting 2 notches in the base of the straw. Fifth, this may be a negative to some but I'm only bothered because I hate false advertising. This thing only holds 32oz of fluid. I just measured again while writing this.

Now the positives, I LOVE this thing! I would absolutely buy another one. It appears to be very good quality, despite the slightly loose handle. I love the metal cup and the hard plastics parts. It keeps ice for hours, depending on how much you put in. Some days I will put a dozen or so large cubes in at 6am when I leave for work. By 4pm when I leave work, there is still a few small cubes left. This is with refills of cold water from our offices water cooler.

I have used travel mugs for years. The mugs I used for years were made by Built but their clear tops get so grungy because they are so hard to clean. Plus you can only buy lids that fit from Built for $5.99 plus shipping. The Hydrapeak mugs have great lids which are spill proof, and are easy to clean, the tumbler fits nicely in the car's cup holder and the handle makes it so easy to handle And it keeps my drink cold for the whole day. What a great buy!

Who needs to spend $50 on a Stanley when you have a much cheaper alternative here. This is my everyday water bottle and I'm obsessed. The color is gorgeous and it keeps my drinks cold for days.

Forget those high price cups and fighting with that twist off lid! This is the cup everyone needs! Sturdy, grippy and the bottom has a rubber stopper so it doesn't slide or scrape in the bottom. It also comes in a variety of colors. Love this brand!!
