Does Not Fit DC07 properly
936148
The clamp end of this hose that "slides" onto the wand part of the vacuum is WAY TOO TIGHT and does not slide up and down the wand at all.  I have a DC07 model vacuum this is supposed to fit, but it does not work like it is supposed to.  I'm at the beginning phase of returning the product and hope to have a replacement that fits.  I don't think it is the seller's fault as packaging indicates this hose is for the model vacuum I have, but the aftermarket specs are obviously off here a bit, and the end result is that it just doesn't work out.  I may have to fork over the extra money and purchase an actual Dyson brand for a replacement.  The hose itself seemed to be good quality, though...just wouldn't fit properly.

Presta valve fitting was oversized.  Would not barely fit my CO2 canister and it stuck on my Schrader valve adapter. I actually removed the valve body when attempting to remove the adapter.

Be careful- screws that came with this handle do not fit in the Kohler GP77759 valve! I broke the screw off in the metal plate that is on the valve. Removed the valve to make sure I didn't screw it in at an angle and the screw doesn't fit! Had to buy a new plate and use the screws from my old handle. Very frustrating.

Well Made, But don't fit. - I bought these hoping they would work in a very old Arca Swiss B1 ball head.  I wanted the safety stop screws, hoping to avoid the danger of my camera siding out of the clam'.  Unfortunately, my old, old clamp measures 60mm.  The space between the safety stop screw heads is 59mm.......... Too bad.  I'll have to return them.  NOTE: this plate would work just fine in one of the newer Arca/Bogan type clamps that have the milled slot for the safety stop screws, BUT If you have a very old Arca Swiss ball head, be advised that this might not fit your clamp.

It doesn't fit the 2017 9.7inch models. Some postings misled me buying in a hurry. Be aware!

Did not fit, though my model was listed. The ends appear to be the same but there is a very small difference in the shield around the electrical connection. Tube slipped into position but would not slide completely in position for it to snap in place.
I was able to modify the shield with a sharp pocket knife to make it fit. I would not recommend you do this, I needed the part and was not willing to wait for a return.
Construction looked great.
NO where did it say it was from Dyson, this is a knock off of the original.
NOT a Dyson product.

I bought this shield for my Archos 80 G9 250GB version but the back shield does not fit exactly the back of the device.  The holes for the USB and vent do not align properly.  Therefore, I had to dispose of the backside shield and used only the front shields. The description should provide clearly this information.

Defective design or straight-out lie? The version specifically made for the Honda VTX1800C simply does not fit the Honda VTX1800C! The right lower mount doesn't clear the brake line assembly, and the U-bolts are too long & hit the back of the radiator even with spacer installed (see photos). Oh, and the instructions are vague and sometimes contradictory.

My return is in en route, and I'm cautiously optimistic Powersport Superstore will process my refund promptly.  Meanwhile, I've ordered and installed a great set of National Cycle Paladins on my bike.

Purchased this to replace the cover on a Z3 Compact D5803. Neither of the two I received fit correctly. One of them is (glued?) visibly out of alignment and the other won't seat properly in the device. The straighter one is off center so the cosmetic portion is 1-2mm too tall and doesn't fit in the recess.

This does not fit a 2007 (early) Chevy 2500HD despite the description listed.  Purchased Diften 615-A0006-X01 as that photo matches the old one I pulled out.  The screw holes do not line up on this product as other buyers have stated.

I had to return the item because the connector orientation was not correct.  I tried to contact Four Seasons, but did not receive a response.  I sent pictures showing the difference between the original unit and their most recent replacements.  I have used this same part number in the past on other Dodge Omni's that I own and they both fit properly.  Something had to go wrong during the manufacturing process with the tooling fixture.  I was really disappointed.  I still need an evaporator.

The product does not fit Nikon D7100. The screw in the bottom of the case is not in the right spot to fit in the bottom of the camera. The case is nice quality but I will be returning the product.

Doesn't fit my 2.5 gal wedco gas can. It'll go in if I'd force it but doesn't go in snugly, thus allowing gas to evaporate eventually. This of course defeats the purpose of capping the can. I returned these caps to Amazon. I went on eBay and found an OEM cap model 84002 for about the same price and I'm now a happy camper.

The silicon fits perfectly, but mine came with the batman print an entire key row off-center (it's shifted to the right). It's bothersome - I'll probably replace it when I see a cooler design/pattern.

I will be returning this item. This is a VERY NICE side cutter.... if it fits on your machine. It didn't fit on mine. After reading the reviews (post-purchase), I discovered other people had the same issue.

Update: I went to the Brother Website for details on which machines this foot fits. See below:

Does not fit. Missing the extra cord to work.

Bought this but it didn't fit. The actual grips should be grooved IN but it is bumped out so they do not sit flush and cannot be installed withiut using  dremmel and cutting away. After 2 hours of gently holing out the grips they finally fit.
