The Amazon compatability checker is worthless

This item does NOT fit a 2006 Mazda 3i, not in the front position on a federal emissions model anyway.

Also the one I got was clearly used and put back in the package, although this is probably done by a dishonest customer and not Amazon.

Is there any product support?
All it says is Not connected to ECU
And amazon is just as bad. You click the link for contact to warranty and it just opens another page and tells me to log in again.
It is a never ending cycle.
Its all pathetic.

Very dissatisfied with this item and returned it. Amazon should do a better job ensuring the acceptability of products that are sold via their platform.

Both cables simply don't work, I thought Amazon would atleast produce a functional product.

Version 5.05 simply not reliable enough to use. The program crashes regularly, often taking my iMac down with it. When it does work, it adds spurious characters to my dictation, particularly after a "new paragraph" command. Unfortunately, I didn't scan the Nuance forums before purchase. The problems experienced by others with this version have been extensive and are ongoing.

Worse, I bought it via Amazon download, which means I can't return it.

It didn't work.  Amazon has failed me.  My echo died and they refused to help me and it's their own product.  I can't wait for Google to come out with their version.  because of this fiasco, I will not be renewing my Prime membership. Awful customer service.

Item does not work. I even updated the drivers and the buttons still only right click. I contacted the seller and they only offered I send it back to them, they will test and then determine if it doesn't work. Another example of a seller trying to push their responsibility onto the amazon guarantee.

Doesn't work (Amazon is sending a replacement) and dealing with the customer support for Monoprice was very unpleasant. I sure hope the replacement works as I have already re-wired my entertainment center!

I have followed the instructions to the letter and even installed two sets of batteries but the guitar refuses to sync with my Wii U. The manufacturers website is useless for help as it does not allow for the creation of a an account when registering (It keeps returning to the create account page). Their FAQs do NOT cover if the process of syncing fails.

One consumer site suggested it might be the USB dongle as the culprit but now I have to pack up and ship back a Christmas present for a piece of junk dongle.

I am fed up with electronics that simply do not work and companies that do not provide adequate support for them. Please, avoid products from Mad Katz

For the most part, I've enjoyed almost everything I've bought from Amazon, including Amazon basics and a number of Kindle devices.  However, this item, "Fire HD 10" Tablet" is an exception.  I'd give it 0 stars but the review system won't let me.

The cursor is often about a 1/4" from my finger or stylus.  Apps, including settings for the fire, will suddenly drop back to the "home page".  Not only is it almost unusable, it's also slow, although I expected it would be a little slow.  I tried working with an Amazon representitive and we ended up clearing the device (even though my apps were on a memory card) but on loading everything back up (which is a problem for me as I have limited internet) the same problems started happening.

I have an Asus ZenUI 8" tablet and it works flawlessly, with the same memory, same apps.

Thanks, Daniel R. Rhodes

Using amazons app for vehicle fit doesn't work, ordered 2 items in lighting that said it fit my vehicle, neither items fit!

Unlike the reviewer who got a working model after 6 attempts and was assured that Amazon had removed their damaged inventory, I received one of the broken ones. I would like to return the tablet too, since there are other models that have working keyboards. My transformer 101 was a total workhorse. I am not willing to continue to pay the $15 return shipping until I get a working model. After reading the reviews that suggest this keyboard is a piece of crap, I may have to change my allegiance. Bad Asus. Bad Amazon!

I tried this dongle/ adapter with three different Logitech mice, all displaying the red unifying or compatibility symbol.  It did not work with any of them.  Overpriced.  Garbage. Inability to return or replace is another reason to avoid this item.

It did not work for me at all.  Had to call Amazon to make an arrangement to get one that would work

How can I write a review then after several downloads and attempting several times to install it with failure each time.  I realize it is a $00cost and if the item didn't sound what I was looking for I would scrap it...1 more time with help from Amazon..
