Sipraw 12 oz Coffee Mug Product Review
Size
I drink hot beverages regularly, but I don’t drink a large amount. So finding a 12oz coffee mug has been a dream! Other travel coffee mugs are just too big and bulky for my needs. This one being on the “smaller” side is absolutely perfect for my needs.
Insulation
I am a notorious slow sipper. Between working and being a new mom, having something hot is starting to become a foreign concept. So it’s really nice to have a reliable product to keep my coffee hot. Their insulation keeps liquids hot for 6 hours and cold for 8 hours.
Price
This is a top notch product. So the fact that the coffee mug is only $20 is insanely awesome. The 30oz tumbler is $25 and the 40oz tumbler is $30. These prices cannot be beat for the quality of product that you’re getting. Better yet, be sure to use the Sipraw discount code DONNAGAILBLOG for an additional 10% off!
Button Push Top
I love the push top! Having a 10-month old, he is starting to be curious about what I’m holding. The push top makes it easy to quickly close off the hot liquid before his little hands get to it. Also with it being leakproof, I don’t have to worry about him knocking it over and making a mess.
The only very minor ding to this rating is that I have noticed that it is harder to push the button if you let your hot liquid sit in the mug without releasing the pressure from the steam.
Look and feel
Overall I am very happy with this product. It’s easily cleanable in that putting it in the dishwasher gets all the way to the bottom of the mug without additional cleaning. It’s compact and fits in my lunch bag with ease. Even when it tipped over in my bag, it never spilled. I love putting my favorite Expedition Roasters flavors in here.
FAQs about Sipraw’s products
Are Sipraw products dishwasher safe?
Yes they are. But for product longevity, handwashing it would be better.
How long will the Sipraw coffee mug keep my beverage warm?
Sipraw’s products will keep your beverages hot for six hours, or cold for eight hours.
Are Sipraw products truly leakproof? It seems like everyone claims this but isn’t.
Yes Sipraw tumblers and mugs are leakproof. They are also double-insulated so you won’t have to worry about your cold beverages “sweating” either.
The pop top on my Sipraw coffee mug is a little hard to press. What’s going on?
If you put your piping hot coffee in your mug and then let it sit for a few minutes, you may find that the push button is harder to press down. That is just because the steam from your coffee is causing some internal pressure. Either loosen the lid or press down with a bit more pressure on the button and it will give. Personally I recommend that you leave the push top open for the few minutes after putting your hot beverage in just so you don’t run into this issue.
