I don't feel this product is better than a regular toothpaste which I used to use to clean my sneakers. It doesnt foam up, doesnt clean very Well. The brush is so stiff, may hurt your shoes. Not satisfied.

The item, I received, which was sold by Mowtownusa and Fulfilled by Amazon, was a 520-590 Stens Fuel Pump or a knock off of one.  I ordered a 808656 Genuine Briggs & Stratton Fuel Pump, and didn't get it.  Well now,  it had a printed sticker on the plastic bag it came in that said " Genuine Briggs & Stratton 808656 Fuel Pump, New"  with fuel pump inside that I can get for $7.00 + free shipping elsewhere, and it looks exactly like what I received. Also, a Genuine B&S Mikuni 808656 or B&S Mikuni Fuel Pump 808492 will have the B&S logo, the Mikuni name on the back of the pump and a part number on the body of the pump; they are made in Japan, not China.  Buyer beware, look at your received item and item pictures from the web to make sure you are getting what you are paying for.  I will be returning this non-genuine item for a refund.

I don't know what to think of this bracelet and this merchant. I have two other Alex and Ani bracelets in gold-tone that I know are authentic. The one I received from this merchant may be a knock-off or used...or both. The bracelet itself is not silky smooth metal like my others. No scratches...just not smooth. The finish itself looks like it might want to discolor after being worn a few times. The claddagh charm does not have a proper finish like its counterparts on my other bracelets. There was no box, just a cheesy black velvet drawstring bag.  After reading about a previous customer's hassle with her Alex and Ani order from this merchant, for $20, I've decided not to waste my time returning the thing.  What I do plan to do is complain to both Amazon and Alex and Ani that a bad company selling knockoffs is penetrating a very large marketplace. Unless and until I receive proof in the form of a valid invoice for this item between this merchant and Alex and Ani by August 31, 2016, I will pursue my complaints.

After I compared the one I received with the battery that came with my 5D Mk II, I saw all the signs that people have warned about counterfeit batteries: No serial numbers stamped on the label or in the little box on the left side, The fonts are all noticably different, the blue part of the back label has choppy looking corners instead of perfectly rounded corners, the black plastic isn't as shiny where the original battery is shiny, and it doesn't slide in and out of the camera as easily as the factory battery.

It took a charge and registered in the camera, but now I'm wondering if the thing will last very long or explode in my expensive camera. Even the packaging looked like it was from Canon, so the counterfeiters have this battery faked very well by now. Beware of seller "columbususa" since they were the supplier on my order.

I recently bought a 77mm lens cap here on Amazon that was supposed to be genuine Canon brand too, and it is also a knock-off. I'm really getting pissed now because I specifically sought out genuine Canon products and paid their premium prices.

Update: This morning I looked at the packaging the battery came in, and at first glance it looks like a genuine Canon box complete with instructions, but the Canon Website indicates that all genuine Canon retail products come with a hologram on the packaging that changes color when viewed at different angles. This counterfeit box contains no hologram at all, and the cardboard and printing is kind of dull compared to the high quality boxes and ink used on genuine Canon products.

Also, the yellow plastic cover that snaps on the bottom of the battery is not as stiff as the original, the color is different, and again, the fonts on it are slightly different than my original. All indications point to this being a clever fake.

Canon's own Website acknowledges that there are counterfeits being sold as genuine, so take caution when buying these. I really want to return this battery, but I don't want to pay shipping again and pay restocking fees or whatever other bureaucracy they use to get more of our money.

Pretty sure the item I received was a knock-off, no branding on it, and I have a j/fit from the store, it had a nice smooth surface coating so that it was durable and didn't shed bits, that's what I liked about it. This one I received had an uneven surface, no smooth coating, and it felt a little wider too tho less sure about that. It was OK, but had offgassy smell and for the price I want to genuine item. Returned to Amazon

I ordered this for my brother and he was unhappy to receive the knock-off looking version sold by VBE that goes for a few dollars cheaper: http://www.amazon.com/Kinect-Sensor-Mount-Clip-Xbox-360/dp/B005IU8A5O/ref=cm_cr_pr_sims_t

We are in the process of returning the item and will simply have to purchase the item in-store.

Please feel free to advise if you have ordered this from Amazon as to whether this is a known issue or whether we experienced a freak accident and people are in fact receiving the PDP brand product.

I have ordered Streamlight Nano's in the past and think they are an outstanding product.  During this particular order I received one which after using was an obvious knock off.  It came in the same packaging as the regular Nano, and appeared almost exactly the same.  The only difference I could see upon close examination was the lettering on the light was a slightly different size from the real one.  The knock off had some type of hard plastic casing instead of the usual aluminum, and when you twist it to turn it on there is a significant difference in the smooth feel that you see on the real one.  I contacted the company and they agreed to take it back and refund no problem but for an item of less than $7 it wasn't really worth it to ship it back.  I doubt the company had any idea they were knock offs, and I found on google there are other reports of knock-offs going around.  Just be aware.

I received a cheap knock off. I have store locally (Nelson Tactical in Green Bay, WI) with the real deal. When you compare the two it's easy to see the difference. I purchased one of these bags from here because I thought I was getting the same quality for less. That was not the case. The zippers on the one I purchased from here are noticeably cheaper quality, and my bag came with an 'NRA logo' on it that was not disclosed prior to sale nor did I want the logo.

Be careful !!! the seller shows one in picture and sent me a different one. I don't even think it's an original product probably some Chinese copy. Mine looks like plastic. LOL.  You can see in picture attached original on the left cheap copy on the right side.

Got a cheap knock-off copy of a real sog key.
You can tell straight away that the key is not original not just from the packaging but the sog lettering doesn't match sog's lettering.

I was led to believe I was buying an authentic pair of Ray-Ban's but the pair I got were fake.

I own a legitimate pair of these shoes, and decided to buy another pair as a backup from here. Upon opening the package, I noticed that these were knockoffs for the following reasons:
1; The shoe box is slightly smaller than the legit one, and didn't have a black satin bow.
2; There wasn't a dust bag for the shoes.
3; The flimsy fabric, lining, and large brand tag, and  stitches.
4; The terrible gap where the sole should be glued.
6;Red soles.

I have a legitimate pair of Bordello Giggle, and took side by side comparison photos, but I don't know how to post photos here.

My mother ordered a Fennekin for my daughter for Christmas using this link, and the one we received was a fake. It did not have a Tomy tag on it and was poor quality. I discovered this mistake because I accidentally told two family members to get this for my daughter. My sister got her the authentic one from another source.

The orange fluff on the ears was only attached at the bottom and not the top. The colors were off, and the mouth seam did not line up. The black outline of the eyes also looks strange.

If you receive one that does not have a white tag that says "Tomy" it is a bootleg fake. I'd return it but I don't have the heart to tell my mom she ordered a fake. We just call the fake the real one's evil twin.

The ones I received have to be knockoffs. I've bought multiple sets at a big box home improvement store and they're wonderful! These ones were cheap and that should have been my first indication that it was too good to be true. Firstly, the ones I bought in-store were flexible. Like, silicone baking mat flexible. The ones from Amazon were stiff and plastic-feeling. Secondly, the ones from the store were clear; the ones from Amazon were a weird yellowed semi-transparent clear. Lastly, the pads on the bottom of my store bought feet are very well attached and have a small hole in the felt that does not extend all the way through the bottom of the silicone-like cup. On the Amazon ones, the felt does not feel like it's very secure to the cup and the small hole extends all the way through the plastic, making it so they'll slip right off the chair. Fail. I'm returning these and buying them at the store again.

Total knock off wasn't even close to the real thing
