VEVMAX Premium AI Designed Coasters - Ideal for Hot Drinks on Coffee and Dining Tables - Funny, Cool, and Cute Coasters Set - Protect Surfaces Durable and Thick Drink Coasters Astronaut (6-Pack)

These bookmarks are great! I was looking for something better than just library quality bookmarks. These are velvet and have nice but simple designs. Great for the price and I would recommend them for anyone who read books often.

Perfect. Exactly what I was looking for. Great quality for the price

I was curious about the AI technology used to make these and to see for myself how they keep your drink hot or cold using the reflective technology. They came in a nice decorative box and have a soft surface on the bottom that will not scratch your table. I am anxious to see how well they work as far as the advanced technology keeping drinks hot or cold, but regardless they are a pretty nice set of coasters.

I really love the spacey feel and design of these bookmarks but there are a few design issues that make them less than 5 star worthy. There are random imperfections in the front plate over the design that are obvious air bubble issues that detract from the designs. The velvety backing also sheds slightly, not sure if that will settle or the quality is low enough that it will eventually just bald or disintegrate. For now I am not using them in books that I would overly mind the particulates, but until I feel more confidant in their durability they are not going near my textbooks, which is a pity. If nothing else they will make for wall adornments or desk accents.

These are AI generated astronaut images and they are pretty fun. The images are very detailed and colorful. As coasters, they are shiny, so they don't to much in the way of absorbing, but they will protect your surfaces. Fun little coasters overall. Recommend.

They look durable and if you like a space theme mixed with sports theme then these functional coasters will fit the bill.

I like these but the felt rubs off a bit.

This is a nice set of six coasters with creative pictures of astronaut's playing sports, strumming the guitar, or sitting and eating on the moon. They have a major flaw in that the top surface is not permeable and if you place a drink on it that is sweating due to condensation, the water beads up on the top of the coaster. So when you pick up your drink, the bottom is wet and eventually you have to dry off the coaster. If you are using this for a drink that does not have any condensation (such as a hot coffee), they work great. But if you put an iced drink on it and let it sit for a while, you'll soon have a very wet coaster.It does come with a nice case that holds the six coasters, and the bottom of the coaster is a foam padding that does protect your table top. If you use these on a glass table or with hot drinks, they work great. But a cold drink on a wood table may be a problem as one of the main reasons you use a coaster on this type of table is to prevent the condensation from ruining your table.One other think I didn't like is the "keeps hot drinks hot, and cold drinks cold" claim. As the coaster only acts as insulation between the cup and the table, it really won't keep your drinks at any specific temperature.If you understand the limitations of these coasters (the lack of permeability) and mainly use them with hot drinks, they will work nicely. Just be aware that cold, sweaty drinks will not be absorbed in any way with these coasters. I thought the overall quality of the product was quite good and did not have any bubbling like another reviewer had.

The box they come in is the storage space for your coasters. The box is pretty plain, and should do OK over time.The coasters are fun, they have the quirky images with a plastic/resin top.The foam base does an OK job at stopping slippage while a cup is on.They easy to clean and a damp clothe gets rid of the cup rings.Overall, they look nice and add some interest to coffee time.

The media could not be loaded.  The listing says these have a liquid glass surface - it doesn't look or feel like glass, it just doesn't have the weightiness that glass does, it's more like Melamine. The listing also says it has an MDF middle layer which I believe to be accurate. The bottom layer (the one in contact with the table) is a sponge-like substance, so I think cleaning should be restricted to wipe rather than immerse in water - I certainly wouldn't put them in a dishwasher.All that being said, these are fun coasters - I particularly like the astronaut having a cuppa and donut break - it's hard work in space!Do they keep hot drinks hot and cold drinks cold? I can honestly say I haven't noticed any difference.Unbreakable? Probably. Unstainable? If it is a thin glass layer then also probably. Unscratchable? I haven't tried that hard, but probably not, I mean, you can scratch glass, right?100% AI designed makes these actually quite interesting, and I do like them, but they're novelties and I would bring them out at parties or barbecues but not as everyday household items.At £15.97 (as at 5 June 2023) these aren't the cheapest novelty coasters you'll find, but they're probably the most fun.

They look really nice and does the job.

Nice set of themed coasters, the spaceman design in various posses is cool. They have a felt type bottom and smooth top. Can't say if they did keep my drink colder on a very hot day outside but they look cool. Come in a nice storage box.

These coasters arrive in a nice looking black cardboard box with a magnetic latch on it. It's a very professional looking packaging that wouldn’t look out of place as a gift for someone who enjoys space and astronauts. The quality of the printing on the coasters is very good, they’re very bright with excellent colour separation and all the edges in the art are crisp. The printing is easily on par with the custom printed ones I've purchased in the past and I was impressed when I first looked at them.The sponge-like foam bottoms of the coasters do a nice job of keeping it in place even on glass and granite surfaces. The MDF mid-layer looks laser cut and it does look a little rough but you can't really see it in normal use, it's only if you pick them up and have a close look.The top epoxy resin surface is rather slippery and it gets worse if the container on top of it is dripping with condensation or spillage. Even a small amount of liquid has the coaster suctioning to the bottom of my low-ball glasses. Which is frustrating as it falls off the table when it unsticks from the glass. They’ve tried to side-step this flaw in the product by saying it's been designed specifically for hot beverages, but who uses a coaster just for hot drinks?These are without a doubt very awesome looking drinks coasters using a unique source for the art, but the issues with condensation and the various false durability claims from the seller are problematic. These aren’t any more durable than any generic printed coasters and to my surprise they even arrived covered in small blemishes right out of the box. All the top layers on the six coaster show some air bubbles under the surface. Three of the six coasters arrived with scuff marks all over the top layer. Even the ones that arrived in decent condition have started to show some scuffing from the bottoms of ceramic mugs. So I'd take the claims of these being unbreakable and unscratchable with a grain of salt, these will absolutely scuff up just from normal use with coffee mugs.They look great but I’m not sure how long they’re going to last if I'm honest, so these are a cool concept ruined by a mediocre execution with regard to the quality of materials surrounding the printed designs.
