Easy to use, simple to clean!

I have to admit I've been on a search for a simple, easy-to-clean, easy to use on-the-go water bottle. Some of the ones that were easiest to drink out of while driving or spill-proof while traveling, were difficult to clean. Others had straws that slurped and didn't flow well. Some were very wide or had twist-off caps that were awkward while driving.

The Zak! HydraTrak insulated tumbler isn't perfect. For instance, I wouldn't throw it in my tote bag with books and my tablet, but it does have a lot of nice features.

1. It's very simple to open, and simple to clean.
2. The straw is easy to drink out of while driving and quiet when in public places. No noisy slurping.
3. It doesn't leave a condensation puddle around it on my desk, or dripping off the bottom onto my dress clothes when I'm in the car.
4. It fits nicely into my car's cup holders, though it doesn't fit into my stroller's unbelievably-narrow cup holders (which really translates to only fitting disposable water bottles.)
5. It does stay cold for a long time. Not for hours and hours, but more than long enough to drink the water at a leisurely pace if I'm busy.
6. The silicone bands make an easy way to track my water intake (which I'm terrible about) by sliding them up to the top of the tumbler.
7. I like the look of it. It's sleek, colorful, and stylish.
8. It's comfortable in my hand, a nice size for holding and drinking out of. The silicone bands also help with traction so it doesn't slip in my hand.
9. 20 ounces is a good size for a water bottle. I like it better than the 16 ounce size I've had before.

There are a few cons. Just a few.
1. It isn't completely spill-proof. The straw feature makes it somewhat tip-safe in a vehicle. If you remove the straw and close the little plastic spout it's even more tip-safe. But if you drop it, I'm sure that white gasket-lid can slip out of place and spill. I also wouldn't toss it into a tote bag with other items.
2. The bottom silicone band tends to shift up or down when pulling it in and out of my cup holder. (Not a big deal at all.)
3. I have yet to convince my kids that they can't share this water bottle with me, since I'm tracking my water with it. They're starting to understand they can't share it with me, but they don't really understand why. They just think I'm being selfish.
4. There isn't a handle or strap I can just slip my finger through when my hands are full. I really need to save a hand to carry it.
5. I'm worried the straw will wear out before the rest of it. I hope I can find replacements.

I've been using the HydraTrak tumbler at home, in the car, and at the county fair. It has been working really well for me, and I'll be looking for replacement straws to have on hand. I like it so much, I even went back for it when I left it sitting on a table at the fair. I was relieved to see it still there.

I see that Zak! Designs has a HydraTrak tumbler with a lever lid instead of a straw. I think I'd like that one even better than the straw version.

I love this little thing! Works great, it is super easy to use. Some people reviewed this as being hard to hold or awkward, but I didn't have that experience at all. Easy to clean also!!

I love this machine! I've been using it for several months, and now that I'm used to it, it's very simple to use, clean, and carry. Highly recommend.

Several reviewers have commented that it uses a lot of detergent. I've found that it really helps to do the whole floor with plain hot water before adding any detergent at all. Maybe my floors are exceptionally gross, but I can't believe how much dirt I got up with plain water!

But here is the best part...by using plain water first, you have created a damp carpet. When you go over it again with the cleaning solution, the damp fibers will be naturally "thirsty" and will wick the detergent deep into the carpet where you really need it. It's the same principle that a watercolor artist uses when pulling excess paint into a slightly damp "thirsty brush." It works! I got so much more deep dirt out with this method, and saved soap in the process.

So nice and easy to use/clean.  I am very happy with this purchase!  The glass is slightly fragile, but most coffee carafe's are.  I'm actually happier with it than I anticipated.  I used to use a French press but cleaning was a hassle.  This made my morning routine much easier.

I've seen these in stores for years, and always wanted one.  My fear was that it would be a pain to clean.  I stumbled on this while shopping on Amazon for White Elephant (Yankee Swap) gifts.  The reviews and question/answers here sold me on it.  Ease of cleaning was the only thing I was worried about... and the reviews/answers here on Amazon allayed that fear.

It works great, if you follow the directions!  Pre-heating is a MUST.  I didn't have any non-stick cooking spray, so I put some olive oil on a paper towel and coated the surfaces with oil after pre-heating.  Everything came out perfectly!  I'm amazed at how easy this thing is to clean!

The instruction booklet has some great ideas for breakfast sandwiches.  I'll be using this every morning now... instead of going to McDonald's.,,, saving me five bucks every day!

So easy for my young kids to use and very minimal mess. Easy to clean up when it gets on the table.  My kids love them!

We LOVE the Coldbroo! Seriously, this thing is so easy - easy to use and easy to clean. I bought it for my boyfriend, who loves making cold brew at home, but his DIY method always made a huge mess and took forever -- we made concentrate on the weekend, and would always run out by midweek. With the Coldbroo, we make concentrate two or three times a week, and it takes no time at all. Makes fantastically smooth concentrate, and clean up couldn't be easier -  I love the simple design. The only downside is I am nervous I will break the canister, though I will definitely buy another if I do =)

Amazing!  Works like advertised and cleans easily.  I just wipe down the underside of the top and either wash by hand or stick the bottom and blade unit into the dishwasher.  Great product!
