Simply put, this is very good for what it does at this price point. I purchased it to make outline sketches for watercolors. I did not need detail, just proportion and form, and found that I could get a fair amount of detail anyway.For those with concerns about the app, it is not needed, you can use any picture.For those that could not nee the image, make sure you are looking through the glass at your paper, and tracing the reflected image from the screen. You may need to adjust the lighting of your room or screen, there needs to be more light in the screen (brighter), but you still need to have light in the room.For those concerned with 'scratches', the plate comes with two protective films that are easily scratched to keep it safe when shipping; take both of them off.For those concerned about the color, yes, the polarized plate has a tint, which is normal.TIPS: adjust screen brightness based on room brightness; you need a balance. You can move the image around on the screen and line up the paper to make drawings that are larger than the screen image. Turn off auto rotate on your screen to keep alignment where you need it; this can only be done in some apps like Gallery.Overall, exactly what I needed for travel and getting proportions right for sketches.

First of all, the app needed to make this product work has not provided details about its privacy practices and handling of data to Apple. Since you have to use your cell phone or tablet, this was a red flag for me since the developer was from another country.Next the projected image is about the size of your cell phone screen. Way too small to be very useful except for the most basic of images. You can try to piece the image together or sketch one section at time, but I doubt that would result in a great image.While it's not terribly difficult to figure out how to put it together, there are no directions. And the app seems to decide arbitrarily that the file format of the photo you're trying to use is not supported. Took two photos of same image, same time, same iPhone. One was fine. The other was invalid format. Not worth the frustration. Deleting the app and returning it. Very disappointing.

So this was easy to set up and use. I actually really like the case it came in. keeping to keep storing in it when not using. Very nice. Then the pieces are easily put together and I can see my screen reflected fine and can trace. Can't do large items because it is only so big but that is ok. I also used not a device. You can't see the reflection of a photo if it is just there. But if you shine a light at your paper it reflects and then you can see it for tracing as well. So it works good for more than just phone, as long as you have light. I think this is pretty neat and easy to use. I actually got it thinking of my 5 yr old. He loves coloring and drawing and I thought he might like this too. He was excited when I showed him. He doesn't trace as well as I would but the practice is good!My rating5 star - I really like this item, really made me go wow you should get this4 star- I like this item and it is fine, but didn't go wow you need this3 star- this item is alright but has a few flaws2 star- quiet a few flaws I would totally go somewhere else1 star- junk no good don't waste your time.

Just as advertised. If you need a larger picture then use an Ipad

There is a lot of hype on what sketch lenses can do. Especially cheap ones. There are pros & cons depending upon what you need. If you're looking for a magic wand to turn you into Davinci, then take some classes instead. If you already know the fundamentals of art, and you're looking for something to assist you with technique, this sketch lens may be a nice little "trainer" for your needs.Let's review the Pros:1) Simple to setup2) Decent quality (for the money)3) The lens is clear (don't forget to remove the film on the lens from BOTH sides)4) You don't have to use tracing paper (a few sheets are included) in fact, you probably shouldn't. I found using a solid white paper or artist paper allowed me to see the lens image much clearer than the thin tan tracing paper they supplied in the package.Let's review the Cons:1) The position of the lens (once you have it in the holder) is not accurate. Moves around too much, and was difficult to have full range of motion when drawing underneath the lens. Often the lens, cut off my subject's head or feet because the lens could not comfortably accommodate a standard size piece of paper. Therefore, you have to make concessions with whatever it is your trying to draw, from either your tablet or phone. I used my iPad, and it proved to be a bit too awkward. You may have better luck using a phone instead. Again, you can make it work with a tablet, it's just more awkward in doing so.2) You may need to flip/rotate your image before using the lens. Otherwise, using the lens will be the opposite of the image from your device. This is not really a con, I just found it annoying.3) You will only see the image as bright as your device can make it. Direct light over your device and lens will remove the lens' reflection from your paper, rendering it useless.4) This lens projects your image at a sharp angle. So whatever your drawing, your subject(s) may be at the angle that your lens projected on to the paper. If you don't know how to self correct your perspective, this may be a little annoying to you.All in all, I gave this three stars because I understand the purpose of a sketch lens, and it performed its duties as such.But, this sketch lens could have been designed better, with a few extra notches in the stand to adjust the angle of the lens or the angle of the device. This alone would have allowed for a better perspective of its projected image on to the paper, making it easier to use.
