KUPITM640oz Tumbler with Straw and Lid, 1182ml Stainless Steel Double Wall Vacuum Insulated Coffee Cup, Travel Mug with Handle, Insulated Water Bottle for Cold & Hot Drinks

Hi bought this a couple days ago and have really enjoyed it I love the size and it’s insulation is so good. I’ve had water inside this stay cold for over twelve hours which is better than some expensive ones I’ve used before.However the main issue are the straws. Upon arrival all the straws broke, thats three glass straws and the plastic one which was hugely disappointing and from reading other reviews I’m clearly not the only case. If you decide to purchase this I suggest getting a 12inch/30 cm metal straw separately.

I have a number of this size, type and shape of insulated cup, and this one has outperformed the others, due to the superior design of lid and seals. The lid is pretty thick, so seems to insulate very well, aided by the very snug silicone hole for the straw. Partnered with the straw cap, this seems to dramatically enhance the insulation, and drinks have remained ice cold much longer than the other cups with thinner lids and wider straw holes.I have an ice maker designed for this shape of cup which makes very chunky tubes of ice in 3 different sizes - I used these in this cup on a a warm day along with about 800ml of cordial made with tap water (so not itself ice cold), and the ice was barely altered in size 12 hours later. The cup was filled twice more, again with tap water, with the same ice and only the the last refill eventually melted all of it, by this time more than 24hrs after it was first filled. Granted, that's a lot of chunky ice, so it is likely to remain frozen longer than a few smaller cubes, but it requires very efficient insulation to keep it frozen for 24hrs.I like that it comes with glass straws, so they're heat resistant if I wanted to use it with coffee (though I generally don't want over a litre of coffee on my own).It's not as pleasing to the eye as some others of this style, but I'd always choose function over form if it means I can keep my drinks ice cold for a lot longer.Priced at £16.99 at time of review, this seems a fair price for a really efficient insulated cup.

KUPITM6 travel mug set includes a 40 oz thermal mug, two reusable straight glass straws, one curved glass straw, one plastic straw, a straw cap, a small straw brush and a silicone base cover. The travel mug is made of food grade stainless steel and is double-wall vacuum insulated which will be able to keep your drink hot/cold for hours. It is specially designed for using in the car, but I would suggest you to check the size of your cup holder of your car to see if it fits in. The travel mug is comfortable to hold and leak proof thanks to it's silicone seals. Its plastic straw works for cold drink, but I am a bit concerned of using the glass straws though which can be accidentally broken. The whole set is not the easiest to be cleaned. The mug need a long handle sponge to clean its deep bottom that's not included. The straws can be cleaned by the included small brush. Be aware that the silicone seals need a good clean too. All in all, it's not the best but a decent mug, suitable for travel.

When I opened the box, a load of broken glass poured out all over the side in the kitchen, so that was fun to have to clean up. Turns out the straws are made of glass, and are not in any way protected in the box, they are just rattling around inside, and one of them had smashed into loads of pieces.Setting that aside, the cup itself seems fairly nice, but the handle feels a bit loose and wobbly, and is not moulded to the cup, but just screwed on.

Arriving boxed, unfortunately it is over-stuffed and in doing so, while it was well protected externally, internally i put my hand inside a bunch of broken glass. Both the straws had been shattered with dents on the inside of the box.While bits were stuck to everything, it did clean up fine and in doing so i ended up with a lovely tumbler with a nice matching silicone bottom for grip and a plastic straw with cleaner. The top is very deep and thicker than ones i've used before with a gripped rubber straw hole so it wont leak when knocked over.the tumbler is made of a nice strong metal and the handle is bolted on tight with no hint of loosening long term.

This is an elegant 40 oz cup in a single colour. I have a couple of these and i have to say I have a couple of issues with it.Nothing particularly wrong with the cup itself as it’s metal and huge. The lid is where I start, it is clearly designed only to be used with a straw, no sipping opening on this one.My second issue is that although it came with a number of straws, three of which are glass (I love glass straws for the mouth feel). Obviously these glass straws come with a flaw in that they are easy to break and one of the ones in the box arrived broken. I couldn’t find any bits in the box so it looks like it was packed this way.The straws barely fitted inside the box so very little protection anyway.Its an OK cup but I woul rather the sip option as well.

The size of this thing is amazing, see picture with a normal mug for scale.However it isn't just sheer capacity that makes this impressive, it includes four straws, three of them glass and a brush to clean them.There is also a non slip cover for the base, and a stopper for the straws.The straws are inserted through a cut seal in the top and a really nice touch is that the lid has a multi-start thread! This means that you can better choose the position at which the straw hole comes to rest.The insulation appears to work, mine has been full of ice for the last hour.

This tumbler is a great size and will hold 40oz of liquid beverage. I love using it for iced coffees and to keep up with my daily water intake but it can also be used for hot drinks too. The ergonomic handle makes it easy to carry and the bottom of the tumbler will fit most cup holders.The tumbler comes with many accessories including a cleaning brush, a cover for the bottom base, a cover stopper for the straws, a plastic straw and several glass straws, sadly one of mine was broken upon arrival.The lid is the screw on silicone type which has a cut out seal at the top through which the straws can be inserted. It's a handy tumbler for travelling and for everyday use.
