Too large for Wallplates!  Broke apart in my hands when trying to install.

The HDMI Keystone Coupler was too slightly too large to fit in the wallplate.  When I tried to put the coupler in the wallplate the coupler broke in half in my hands. This happen 2 days after my return/refund ran out so now I'm stuck paying for an oversized (now broken) HDMI Coupler.

Bought this to hang my parents' 65" Panasonic Plasma.  The instructions were terrible which made assembly very frustrating for my father and me (lots of little screws to screw the pieces of the bracket together...better mounts are not made this way).  And it didn't adjust to screw into two studs (16" center) ...had to use longer, bigger screws than the ones provided, and angle them into the studs--very awkward.  This was way more work and took way longer than it should have.  I would not purchase a Cheetah mount again.  I purchased a Monoprice Low Profile Wall Mount Bracket for a 42" t.v., for $25, and was much simpler and faster to install.  https://www.amazon.com/gp/product/B0069MDM2G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I want to warn other customers about this bug shield. I'll post a picture of the cheap mounting screws that came with it. They are PLASTIC. I can not believe this company expects this hardware will hold the shield on the hood, even if you manage to assemble the screw through the hood seal, the shield and into the expanding nut. The head of the screw snapped off as soon as I tried this magical feat. Do yourself a favor and get [four] 1/4in sheet metal screws 1/2in long. it took me 10 minutes to mount this bug shield with these real steel screws.

Pretty frame BUT the little covers for the screws that come with it absolutely DO NOT FIT.  They are too big for the screws provided and thus useless.  Also, IMO they were also pretty ugly, so I didn't use them anyways.  If you plan on buying this plate, don't plan on using the screw covers they give you.

I'm so pissed.  1st of all, The instructions recommend quarter inch bit,  Which is way too big for the anchors provided. Then I realized, after drilling large, unnecessary holes in my wall, that several the parts are defective. The set screw will not tighten enough to mount the dang thing on the wall, theres something wrong with the threading. I probably have to return it, so frustrated I could cry.

Photo is the screw tightened so tight I started to strip it, won't go tighter.

I'm not sure what the designer was thinking when they created these, but getting the 3 switches lined up perfectly (even using Leviton Ducora switches and outlets), having the internal clamping insert put in place so that it lines up, and putting the outside cover on and having something that looks great, is a very painful experience.

The internal clamping insert uses the same screws as the switches and outlets, and is more than just painful to attach. A better design would be to screw the clamping insert into the already screwed in switch and then put the outside plate on that way. But alas, the person who designed this for Leviton obviously never had to use their creation.

I expected more from a named brand like Leviton.

If I hadn't already put in all the single gang wallplates (same stupid principle, but easier to align as there is only one switch or outlet to worry about) I would have returned everything and gone with something that sadly has a screw showing.  Oh well, lesson learned.

Not recommended if you don't want to punch the wall in frustration while trying to put a 3-gang plate into place and have it look like it should actually be there.

Mounted this unit into the studs as directed.  My Thule 2 bike rack doesn't fit the pin size so it's just supposed to wedge between the pins.  This method allowed the rack to wobble severely and could possibly fall off the wall.  My guess is that he manufacturer decided to simply modify this wall unit when they discovered that the pins didn't fit the Thule brand.  This makes for a poor solution for Thule racks.  Might work better with other brands.  I returned this to Amazon, but still have holes in my garage walls that I need to patch.

I purchased the butterfly phone dust plug and did not realize how absolutely HUGE and bulky it was! It is approx. 2"W and very heavy. I have a bigger sized phone (Samsung Note 3) and this charm was far too large to realistically use. It dangled in front of the phone's camera and made the phone so top heavy that I dropped the phone within an hour of plugging this charm in. My phone was not damaged but the clasp holding the charm to the plug broke and the 2 large rhinestones popped out. I'm only giving it 3 stars instead of 2 since I can glue the stones back in and maybe use it as a necklace instead! I cannot recommend this product as a phone accessory.

Not worth the price or the wait.  I ordered these for use with the Wall Control Galvanized Steel pegboard panels, hoping they would fit and be tight.  Not only were they not tight, I had three of the too-lightly welded on secondary stabilizer pegs just break off leaving the hooks to swing freely on the pegboard - precisely what I had hoped to avoid.

I'll just buy from the local home improvement stores and jury-rig something to make them fit tightly - you'd think this would be easy, it ain't rocket science, but noooooo...

When I purchased this, I thought, as the description indicated, that it was a 3M hook.  It also said that it would not damage walls. so i thought it was a typical 3M hook. When I received it, no indication of 3M or any other manufacturer. It also came with no instructions, but they aren't necessary.  The problem I encountered was that when I attached the brackets, a little bit crooked, I tried to remove them to readjust. Unfortunately, the adhesive is so strong, it took all the paint behind it off, as well as an area surrounding the bracket. Also, the paint stuck to the back of the bracket, so it's useless now.  I tried using 3M  strips to the back of the bracket, but it didn't stay up. Now we have to redo the wall.

Bottom line... it seems like a good product, with a firm grip. I HIGHLY recommend that you carefully measure before you attach it to your wall!

I bought this kit for a wall installation. The sleeve was ok but the outside piece flanges were way to big for my needs. Much bigger than the main part of the doggie door. I ended up making it out of wood. Which matched my house anyway. If it was cheaper I would have thought it was worth it  maybe.  I did use the sleeve. The other piece is in my attic now. I am not sure why.

Nowhere in the description does it say that this does not fit NORMAL sized wall plates.
Do not buy. This is a NON-STANDARD size!

Supposed to fit the map lights in my truck according to "my garage" but they are too large and when putting them in, I broke the lamp holder.

Tried to install one of these and when I went to use the plastic anchors provided in the package, they both snapped. I followed the directions on the back of the package, using the provided screws as pilot holes for the anchors, and still they shattered when I tried to screw them into the wall. If you are hanging these and can't find a stud, be sure to stop by the hardware store from some more quality anchors - I'm ordering mine right after I click submit.

these weren't strong enough to hold a large glass plate on the wall and if you have transparent plates or translucent  plates you can see them through the plate. Also, the surface of the plate must be totally smooth.

Was so excited to finally get these for my husbands "Man Cave" but the screws included with the plate were way too big.  I think it's silly that the manufacture doesn't included the correct size screws.  Other then that it looks great!

I ordered two of these caddies because those that hang over the showerheads in my two bathrooms either rust or don't fit. I figured that these would be perfect since the maker of the adhesive was 3M, but I was wrong. Even though I followed the directions meticulously, both fell off the tiled shower walls. The folks at 3M need to include in the pre-purchase information that if the tile or other surface is even slightly uneven, the adhesive won't adhere.

I'm extremely disappointed -- and to top it off, they're not returnable, now that I've opened them and tried to install them.
