I think that the mug is a great idea. This is not an insulated mug. Don't expect it to keep hot drinks hot and cold drinks cold. It is just a plastic cup with a strap. Not worth the price. I was really disappointed in the quality :(

The lid leaks and it is not all that thermal. A cold drink made the outside surface sweat.
It is more of a novelty than a practical item.

The mug i got from this seller looks cool, but mine had like 15 mini holes in the mug that is impossible to poor any liquid in side... good luck

This is advertised as a travel mug,  but it's more like a thermos. There is not a small opening for drinking, only the big opening for filling. It looks nice and all, but not what I was looking for.

I like this lunch tote.  It's made with a nice fabric and looks nice.  It's also a good size for holding larger flat containers.  I was really disappointed when I received it and found that it is not insulated in any way.  I went back and read the description which did not say it was insulated or thermal.  I just assumed it would be insulated since it's a lunch tote.  I can't fault with the seller or the manufacturer for that, I should have read more closely.  But I think it's a reasonable assumption that a lunch tote would be insulated, most of them are.  It's fine if you have a refrigerator to store your lunch but if you don't  - Don't buy this tote.

This mug does not keep coffee any warmer that it would be in an uninsulated mug with no lid. It also gets water inside the metal sleeve when you wash it. This water slowly leaks out after you pour a hot drink into the mug.

Good mug, not insulated which I prefer because I don't want to wait too long for my coffee to cool. Cork hand protector can be removed for washing. Plus I've been trying to avoid plastic containers for food/drink so this was a good find.

Great mug! My only thought is that I'm not sure that ot can be microwaved (and I don't want to test it because it's a nice mug!!).

Cool mug.  Works as advertised.  NOT dishwasher/microwave safe!

This is not a bad "travel mug".  It doesn't fit in my cup holder but I wouldn't deduct a star for that, I should have paid more attention before ordering it.  It doesn't leak and it keeps my coffee hot for hours.  My flip lid hasn't broken, however it can be more difficult than it should be to open, especially while driving.  Also when I drink from it, the flip lid is right in the way and gets coffee on my nose. I have not tried it with cold beverages, so I can't say how long it keeps cold. I'll keep it, but I'll also be buying another that fits in the cup holders in my truck.

While the mug keeps things hot, it can't keep things inside of it. This mug has a lid that just pops off. Put anything above 100 degrees in here and within a few minutes the seal pops off and if you happen to be drinknig it, the hot liquid falls all over you.

Great mug!  Looks great!  Only problem is that it is NOT microwave or dishwasher safe.  Someone got this for me as a gift, so I don't know if that was in the advertisement or not.  I love it, though!

One thing that separates this product from others that are similar is the fact that it is vacuum insulated.  This allows it to keep drinks cold during the hot summer day (hot drinks are not recommended).  In addition, it has a one-touch spigot system that allows you to hold the bottle in one hand, press the button with your index finger, and get a drink WITHOUT putting your lips on the bottle.  I like that because it makes sharing much less uncomfortable with regard to germs, etc.

The only reason for the four stars is that it's not really designed for hot drinks.  I have no idea why, perhaps they don't want you to burn yourself, or the plastic won't hold up to hot liquids, or what.  But I have a Thermos for that, so overall not a really big deal.  It seems very durable.

With good intent, my Aunt gave me this mug; if you want a french press, buy one; if you want an insulated mug, buy one; do not buy this poorly conceived hybrid.
Main problems: grounds in coffee; plastic filter ring; difficult to clean, top heavy.
I'll keep using my dependable insulated klean kanteen; it performs well even after I've dropped it and banged it up; it goes with me everywhere.

It doesn't really keep tea or coffee warmer than a regular cup, which was my main reason for purchasing mug.

not insulated; this is just a cheaply designed item. Put hot water in it, you will burn your hands... and that also goes for cold water. Returned it and got something else (50/50) and it has been working perfectly for the past 6 months.

Although my commute is only 15 minutes long (and I live in a hot climate), my coffee is lukewarm by the time I get to work. Not sure how considering a normal ceramic mug will keep coffee warm for more than 15 minutes, but this mug is useless in terms of temperature control. It does look nice, however, and is very easy to clean.
