Depends on what you want to use them for ...

The printing on these is beautiful. The colors are bright and the black border really sets them up nicely. I can see how these would be lovely framed and up on your wall. I'm sure they're also great for various other arts and crafts.

However ...

I purchased these thinking that they were postcards and I intended to use them as such. Despite the lovely images these do not work well as such. They must be torn from pages in the book. Each page has 4 cards that are attached together by perforations. This leaves two sides of your card with a very unattractive white torn paper "fluff" that you're going to need to cut off. Also the weight of the paper is pretty weak. I worried about sending them as regular postcards so ended up putting them in envelopes and sending them like they were regular letters.

So if you're looking to use these for crafts or framing, I give it 4 stars! If you're looking to use them as postcards ... try a different product.

I bought this because I needed a bunch for spots like the car, bike, garage, spots where they'd get a lot of abuse. They are good but wouldn't recommend them for all day use, bit too thick and heavy. But if you want a spare pair for the car or around the house than yes very good.

check the dimensions, they are very small, which is what I needed - but it might be surprising if you weren't expecting it!

they work fine for a few projects. cheap quality but that shouldn't matter if you're not using them on a day to day basis

3.5.  As long as you don't expect much, these will meet your expectations.  They look good for what I use them for but they do have a lot of flaws you'll have to cover up: chipped wood and such.

I sent these back because they were not as big as I needed. The quality was alright, but if you will be using them for everyday not work the price.

These are good for supplemental gifts for grandparents or for taking them to work to put on your desk. They aren't something I would hang on my walls at home; they just aren't that nice. Fine for the price as long as you know what you're getting.

They are not very soft or comfortable to use, only for looks

They are a bit smaller than you would think.

Good product depending on what you need them for. This unfortunately had too much bend in them while in use.

Not exactly what I expected from the picture, but they'll work.

They were too long for what I wanted to make with them but that was my fault for not reading further. They will work for me with future  projects.

You are getting what you pay for with these. They are good for general purpose stuff but I wouldnt recommend for professional use.

Didn't need them after I purchased them, but I'm assuming that they would work.

I did like them enough to just reorder another set, so hopefully they will come and both will work for a long time to come. Amazon ships fast and they come packed well. The speakers are usb for power and 3.5 generic headphone plugs for most mp3s/phones/computers for the sound output. If you are wanting these for on the go, would have to plug into a tablet/laptop that has an actual usb or use an adapter and they probly eat a bit of power so probly not a good choice. But for someone who has an available usb power source, they work well. I got them for my office where base and a louder speaker isn't ideal. They worked well for that and the sound was clear enough up to a talking level. Turned all the way up was a bit obnoxious with the highs and hardly any lows/bass to go along with it, so if you are wanting a range at higher levels, would give these a pass.

Good for what they are though. Hope the next set works though! Quality control issues maybe???
