Waste of money, is not moon filter.

This filter is literally the worst possible use of your money. It is not a moon filter. It makes everything so green as to totally ruin the viewing experience. If you buy this you may as well just throw out the money to the trash. You can't even return it because the seller (not amazon) will charge you for shipping both ways. Spend the extra 10$ and get something like 1.25" Neutral Density Filter 13% Transmission ND96-0.9. Otherwise you'll end up wasting your money and end up with no filter at all.

Ordered these by accident.

Compared to PetSafe: these are ridiculously thin and transparent, because there is barely any charcoal in them... Not even enough to actually fill each pocket, which means they cannot possibly properly filter anything. They cut corners, literally, to save every little bit of cost on material they could... Unless the odd shape is for one of the fountains... HOWEVER, by not being completely squared, these allow water to freely bypass the filter.

All-in-all, these are an epic design and manufacturing failure.

Since I opened the look-alike bag, I can't return them.

I think they're thin enough to put two together and match a wide end to a narrow end so that water can't bypass the filter and so that maybe these filter a little bit.

I swear I avoided ordering the knockoffs, but here they are and they are not fit to filter anything.

There's no way they'll even last two weeks, although the package, like the PetSafe filters, say "two to four weeks".

There's no saving any money with these over the PetSafe.

They look so similar, clearly by design, you'll have to be careful to not mistakenly order this grossly interior ripoff copy cat garbage.

skip any review that is positive.  this thing is bulky, NOT as bright as advertised and IMPOSSIBLE to efficiently adjust the "spot" feature.
what a joke.

This is not a Watt's product - it's some Costco filter.  Does not work on the quarter-turn filter.  This is the one you push a button to replace.  Very confusing/misleading product description and it took nearly a month for my credit to show on the return.  Read the reviews carefully before purchasing.

The vendor gave me a refund, so that is good, and they get 5 stars for  that action, and 0 stars for false advertising to start with. This filter.... Oof.  It came in a package that said nothing like "this is an IR cut-off filter at 1000nm (which is 1 micron). In use, I can see through this filter, and my eyeball won't detect 1 micron light, so, this is not a 1 micron cut-off filter.  I'm going to try to fire  up my transmission spectrometer, so I can post the actual transmission spectrum.  I bet we'll be disturbed.  I can also literally see that the filter does not have uniform optical  density across the surface. Some places let more visible light through than  others. Ultimately, being sold as "Infrared Infra-red IR Filter 1000nm 1000"  (which is obviously worded to catch as many fish as possible) is false  advertising, and is illegal. This falls under 15 U.S. Code  45, and is regulated by the FTC, and "most favored nation" trade status does not trump this law.  I have fallen for this numerous times since I believed that Amazon really would not allow this to happen, but it's happening frequently, and it needs to stop.

I purchased 9 of these to try to light my 10 foot by 16 foot back patio . Advertised as giving 8-10 hours of light on a 4-5 hour charge . Nope . Only give me 5 to 6 hours light with a 10 hour charge. They were packaged well and delivered earlier than expected . But have a weak solar charging element . I even purchased some Duracell High $ rechargeable batteries $40, thinking the batteries that came with them were weak . To no avail , same results . Sun comes up at 7am & goes down at 5pm this time a year (Thanksgiving) . The lights all go out about 10:30PM & the party is over . I wasted $143.37 for 9 of these ,plus another $40 for top shelf rechargeable batteries (183.37 Total)  & now the price has come down by 33 percent , (No wonder I think they know they have a substandard product and are trying to unload them). Don't waste your money . Get some cheap solar lights from WalBobs & you'll be happier than I am .

Waste of money, unless you just need something for basic dust protection. Does not hold up to sun exposure or moisture.

I just realized that this is an off brand, not ZeroWater brand. These filters last a fraction of the time the ZeroWater brand does. It is very disappointing. I won't be purchasing this brand again.

These are not ATV/Motocross goggles. The lens is thin flexible plastic with about as much protection as a cereal box. It's also clear so they're not really suitable for skiing except on very dark days or nights. But even if the light is sufficiently dark, these things let in way too much wind. I have a really hard time imagining any kind of sport activity these might be good for. I should have looked carefully but the product page is full of spelling and grammar errors. And the box itself is also full of spelling errors. So basically just another poorly designed cheap knock-off import. And the sad thing is, there are so many people out there who are willing to write 5 star reviews to mislead and waste the time of other buyers, and ruin a good honor-based marketplace review system, all because they received a cheap free product.

Yeah, I'm sure I made the same mistake as everyone else who saw "Hydro" in the name "Hydroplanet". I saw it and thought it was meant for indoor grow tents. You know... hydro=water... not air. But this fan is pathetically underpowered for a grow tent setup, especially since I'm using one of the smallest tents out there.
My tent is 36" x 20" x 62", and this fan doesn't work to vent the heat or odor out of the tent (I also have a charcoal air filter, I don't expect this fan to somehow magically clear the smell).
I've been in "veg" mode from about the time I received the fan until now (about a month and a half), so the smell hasn't been an issue before today. But now I'm pruning my plants, and the smell from the plants is much more noticeable in other rooms.
Since this fan performs so poorly, I just had to spend more money to get the fan that I should've bought in the first place. I learned my lesson, and I hope my review can help you avoid the same mistake. Unfortunately for me, the return window is closed, so I'm stuck with this turd of a fan...

Well this telephoto lens is atrocious. Cheap as hell. Was included as part of a Canon SL1 bundle that I bought on Amazon from Photos4Less. It will leave all your photos blurry, and they lie when they say it is a 2x teleconverter. I would say 1.3x MAX. Tried to take a few photos of the moon. Did wonderfully with the Canon 300mm lens. Figured, hey, let's attach this guy and we'll get 600mm! WRONG! After attaching, it BARELY zoomed in any closer, made the entire moon blurry like your vision after raucous college party, and completely threw off the lighting. The only use for this is for magnifying the sun to create those miniature death-rays we all loved as a kid. Actually not even sure it would be up for the task... Do yourself a favor and stay away!!!

This is very poorly made filter, too short first one was torn when I tried to put on filter, second one I have to stretch it, it leave 1 gap top and bottom, when I use it, the foam filter is so porous it really don't serve any purpose. I wasted  money on this one.

What I was wanting was a book on the stages of the moon for 2014 so that I could keep track of the moons stages, instead this was more like a farmers almanac with the moon at it's center. Not at all what I wanted or how the description reads.

What you actually get is a dark blue, red, dark yellow and grey moon filter.
Dark filters don't word well for f/5 telescopes.
I am returning this set.

Waste of money. Save you dollars and by a good macro lens

This is the worst UV filter I have ever used.  I bought it for a new lens primarily as a protective piece, and since the filter is not coated, using this filter ruins almost all of my outdoor shots with nasty green reflections.  Before I purchased this filter, I did not really know that UV filters could produce such awful results since I just buy them, screw them on, and forget about them.  This particular Canon brand UV filter is absolutely worthless.  I have since removed it, and am going to purchase a different filter.

In short, don't waste your time with this filter.  Purchase another brand for your lens.  Canon generally makes awesome products, but they really missed the mark with this one.

I bought this in a double pack along with Moon in My Room - while the moon is outstanding, the Earth in My Room left a lot to be desired. I thought that the Earth would go through phases and light-up during the day and then show the cities lit up at night, all the Earth in My Room does is show the cities light up, and they are very dim and well, very boring. It's a poor addition to Moon in My Room, and frankly, I'm already planning on returning both just because it was not as complimentary a pair as I would have liked.
