I had been using a stack of books to give more heighth to my laptop! I found this stand and thought it would be better than an uneven stack of books! It is great and am using it now.

Instantly improves gas mileage and performance. These are the best air filters you can find. Highly recommend.

My 4 year old loves it. There are many filters you can add to the pictures.

Wow I can't believe the detail you can capture with this lens! If you need super detailed up close pictures, this is the lens for you. Highly recommend.

I have always used the threaded filters on my camera, going back to my earliest days in photography. And we all know the effort it takes to change one of those filters - you have to unscrew the current filter and then screw the new one onto the lens, a process that takes a couple of minutes, at least. Not always ideal. With this set, you have two threaded options: an empty ring (with no filter or glass of any sort) or a threaded UV filter. The other two filters (a circular polarizer and a neutral density 1000) then attach to either of the previously mounted rings magnetically, so that switching filters just involves pulling the filter off and putting another in place - in just seconds. An excellent option in situations where you might want to change filters frequently. In addition, the set includes a convenient carry case, with separate, padded pockets for each of the filters. This case can be worn on a belt, or attached to camera strap (or in my case, the chest harness I use to carry my camera while hiking), which ensures that the filters are close at hand when you need them. My only complaint is that the magnets are a little bit too weak. At one point, as I was setting my camera down, I bumped the filter and it fell off. Luckily, it does not appear that the filter was scratched or otherwise damaged, but if you use these, you want to be aware that they can be knocked off relatively easily. You probably would never have a problem if you only used them in a studio environment, but if you use them outdoors, especially if you are moving around a lot, you want to be careful with them.

Good quality and easy to stack. ND8 and CPL stack well in bright light. I really like the sleek, modern way they all stack together with a cover so they’re super easy to carry while staying protected. Wish they came with a little cloth sleeve though just so the cover won’t get scratched, but that’s a minor thing.

Best money you can spend for your engine, have K&N filters in all my vehicles

As with all other NEEWER products I've used, I remain to be impressed by how great their products are. This one is absolutely no different. The filters are made incredibly well, and the included storage case is perfect for storing any filters you aren't currently using. The filters work well and with such a variety of options, there's a filter for most any situation. It's a lot of fun to play around with the different filters to see what kind of effects you can get on your photos.There isn't a whole lot I can say about these filters other than that they are pretty great and I recommend them if you're looking to take your photography up a step.
