Not sure what this is "Standard" for but it definitely is NOT standard fit for the Tetra air pumps, valves or accessories you'd hope to connect to a Tetra air pump to. Specifically, the diameter is too small.

Missing nut that is supposed to affix holder to top of adjustable height shaft. Of course it is non-standard and can't find a replacement. Had to jury rig a bolt/nut combination that would work. Frustrating  when it arrived and I wanted to use it.

My review isn't necessarily for the filter ... more that I read reviews (and not the FAQ's) only to be lead that these filters fit the P3 Standard. And when I went back to look at Amazon, I see a little spot where the abbreviations were for Adv. and Pro. Missed this to begin with ... only to find that regardless of which product SKU you are clicking the product review goes to the same 90 reviews. A little mid-leading. After what I thought was thorough research I have come up short. Bummer. Getting returned and reordering.

This was for someone else I don't know what they think of it but I gave it 5 stars because it looks like it would do the job.

I was hesitant to make the purchase because I did not know if the "Screw-In" Headphone Adapter would be a standard universal part. I am still uncertain however it does fit my Pioneer and Sennheiser headphones perfectly. I might purchase a couple more in the future seeing they are hard to come by. I rate this part a 10/10.

A use for any position on the table. Standard bridge is nice but this is AWESOME!

this can be used in so many different ways according to what equipment you have.  I am giving it 5 stars for that aspect alone.

This does not conform to the standards of iMac A1419 27" tapes. I dont' think this will be strong enough to hold. I don't have a choice because I put it in already and I needed it done yesterday. So I ended up putting Electrical tape on the top 2 corners and lower 2 corners just to make sure it holds. I ordered from them seeing the 2 negative ratings. I was thinking they didn't do it correctly when they put it in. I have installed this before when I changed my drive and I know what it's supposed to look like. I just upgraded to an SSD so I needed another tape. I was wrong. I should have bought it else where. My first purchase has numbers and are much more thicker and easier to put it. If you are looking for a strong tape, go somewhere else. This is not for you. Notice I added the picture of my iMac. See the tape size on the left and right? The top and bottom? This is not what you are looking for.

It would be nice if the product used standard screwed to mount like every computer case and hard drive.
Vantec seems to think otherwise because the screws that are used are a touch smaller than the industry standard. As such if you have any cases such as the node 804 like I do, you end up with something that cannot be used. It can't be used because the node screws are the normal case standard but the vantec ones are micro sized

The standard battery pack that comes with it is terrible. You definitely need this if you don't want to be consistently charging the battery.

I guess this was a romance? I guess this is completely different to anything I've ever read? I guess. Who would I recommend it to? Anyone who is ready to fall down the rabbit hole.

When I worked for a tech company, I remember the expression: "God must love standards, he makes so many of them...".  When USB came out, I cheered heartily at the prospect of eliminating serial ports, parallel ports, etc., and replacing all with just ONE.  And it supports charging the device!  Unfortunately, the geniuses who promulgate new products have managed to take the edge off that great industry achievement by coming out with incompatible VERSIONS.  Apple, of course, has to make something proprietary to make you stay in the family.  But, I'm talking about the device-side connectors now coming in at least 3 common incompatible versions.  So, I'm stuck with having to find and juggle different USB cables for my Kindle, camera, phone...  That's what I bought this port hub for.  Now I keep the various cables plugged in to it and ready for my devices.  It's important that the device is powered because, although a hub powered by the computer's USB would be more convenient, my past experience is that some devices won't charge on that arrangement.  I also keep my printer and an external drive plugged into this device.  All working great so far.

This cable has a weird connection - not like anything else I've ever seen and certainly does not work with regular TVs or equipment. I have no idea what this cable is used for but not for connecting a satellite or cable outlet to your TV.  The cost to return it is almost as much as it was to purchase and they don't pay for shipping if you need to return it, so be very careful if you purchase this cable that it is exactly what you need.  Ours will be going to the dump.

For some reason, SRAM ships this with a Torx screw instead of an Allen, which is the standard for pretty much every bike accessory on the planet. Rather than committing to carrying one more tool, I paid 50 cents at the local hardware store for a proper Allen screw. But what in the world were they thinking?

Otherwise, this mount is fine, save for being a bit larger in minimum diameter than my handlebars, which was easily resolved with some rubber spacers (not included, but I had them in inventory).

Not sure I like this or what. it works fine I guess.

It functions exactly as I expected it would. I think it's a pretty standard design. IDK... I am not using it the way it was intended. I am using it to click my computer on and off/reset it directly, no button covering it, like one would in a case... I bought another one to replace the jumper I needed to plug into my motherboard when I want to reset the CMOS settings. That was the best idea I've had in a long time... So convenient for someone who manages to need to reset their CMOS settings by hand fairly often. I imagine the only thing to think about is if it'll fit into your case properly. Like I said though... I think it's a pretty standard design. I bet it's what case designers expect people to use.

Probably my fault due to my limited knowledge, but this cable would not work for me since I needed a standard cable connector at one end and I didn't understand the notes with the description.  As cables go, it looks like a sturdy cable.
