Question: Does it leak after weeks of being used? I really want to buy it but I need to know if it leaks
Document: Whenever I need a 2nd to go mug or want a different color, I will definitely buy another one of these. Great product & budget-friendly!
When I bought this, I didn't yet realize how popular this particular brand was. This was my first Copco cup and I want to buy another! I love that the entire thing is dishwasher safe. I also love that it's BPA-free. If you are in a hurry, this is a nice cup. It cleans easily and seals easily for when you are are trying to get on the road. I have used it for hot and cold liquids.
I am used to a very nice thermos with a hefty price tag and since I have two of those and drink coffee everyday I wanted some cheap back up ones because the others are also hard to clean. This one works perfectly, doesn't keep my coffee as warm as long as my expensive ones but I don't need them to. Also they are cheap and super easy to clean, absolutely love it and will probably buy more.
Works great, doesn't leak, and I really like the purple. The plastic sleeve part feels just the slightest bit sticky, for some reason, but it's not enough to particularly bother me. I have been hand washing only, so I don't know if a round in the dishwasher might get rid of the stickiness.
Great cup! I'm extremely clumsy and this cup makes it really hard to spill.I like the paper cup look... and it fits in all cupholders. I used to have a similar paper-looking-cup made of ceramic with a silicone lid, but it leaked like crazy! This one is all plastic and the lid screws on. Seems completely leak proof. The rubber sleeve is firmly attached.I use it for hot and cold drinks.
It seems to be quite durable and the white does not stain. I assumed that my coffee/lipstick would stain it, but it always comes right off in the dishwasher. I read some reviews that say the lid leaks over time. I have not personally experienced this, but I do not use it every single day. It's good to know that the company apparently has good customer service if you do have an issue! I like that the outside has a textured grip.
Pros: Easy to use, easy to clean, can go in the dishwasher and microwave. Replicates the feeling of drinking from a cup. Looks nice. Fits in most cup holders. Inexpensive.Cons: Keeps coffee warm but not hot. If you don't get the lid screwed on right, it leaks.So it comes down to what is more important to you. If you want your coffee kept good and hot, opt for one of the stainless bottles like the Nissan Thermos or Zojirushi.
These are good travel mugs for the price and are dishwasher safe (more-or-less). If you need a cheap mug for use in the car, these are a great option. The only downside is they have a bit of a limited lifespan. After using a couple times a week for 2-3 years, they begin to wear out and the rubber seal starts leaking. They also get stained from coffee a little bit, but many of the mugs I've used have this problem.
Great travel cup for my morning coffee! I've purchased so many cups that leaked but this one does not leak. I've been using it for a few weeks now and plan to order more!
I love this mug and use it almost everyday, I would buy another, but I don't want the clutter. If this ever gets lost or ruined, I'll definitely buy this exact same cup.
Answer: I bought my husband one for his birthday and he's had it for over 6 months now, we have never had any leaking problems with it. We don't really put it in the microwave but we put it in the dishwasher all the time and it's used several times a week. I'm getting ready to buy more actually.
