Wanted it to work for me, but even multiple attempts with multiple bits didn't work

I wanted this to work.  But it didn't. I had some rusted screws on my car holding in the license plate lights that were stripped and rusted.  I put WD-40 on them to loosen them up a while back.  I took the smallest bit, used the cutting side to prepare it, flipped it to the removal bit side, and the bit turned but not the screw. It didn't bite into the metal at all -  it just made a bigger hole. I double-checked my approach and confirmed that i was using the drill in REVERSE mode.  I also tried it again with plenty of pressure to help encourage it to bite, but it wouldn't. With the holes growing in size, i moved up to the larger bits, all the way to the biggest one, and nothing worked.  Seriously disappointed.  Perhaps others will have better luck, but this is what I bought them for, and they didn't do the job.

Cannot get this to work, I have tried twice and disappointed each time

I couldn't get this to work but maybe it requires more technical knowledge?  Maybe better instructions would have helped or maybe the disk I received was defective as it appeared to me.  They refunded the full amount after I returned it so thankful for that.

Tried to 'set' the combination. Does not work. Tried everything. Opened up the second of three. Same thing. Thought for sure I am doing something wrong. Still no change. I guess mine will always be set to 0000. Too bad.

Well, Single-Serve didn't work...
Don't know why and couldn't fix that following the guide so I returned it...
If it works, this would be a reasonable choice

Tried two sets of these. Neither would update or connect properly.

It worked one time and I could never get it to connect again. I reloaded the software and also tried the third party CHIRP software.
I work in the computer business, so I do have some ability to load and use electronics. I'll have to try another cable.

It worked the first time I plugged it in to copy over my utility files from my previous keychain and then the next time I tried to use it a month later all I got was a  a "Please insert a removeable disk into the drive" error no matter if it was plugged into a USB 3 or USB 2 port on three separate computers (1 desktop, 1 laptop and a tablet). Can't even format it to try again. Normally I have good luck with PNY SD cards and an old PNY 1GB drive I bought years ago still works fine, but this one crapped out just after the return date expired.

I bought this strictly for the purpose of ripping audio cd's to iTunes on my iMac. I have to constantly unplug/replug the drive, sometimes several times, to get it to make it through ripping a whole cd. I tried the drive on a Windows laptop and desktop, and it had the same erratic behavior.

Judging from the other reviews it seems most of the drives are good, I just had the bad luck of getting one with the same issues mentioned by many other reviewers. It seems I will have to look elsewhere, as this one is far too much work to just get it to rip a single cd.

Unfortunately this design didn't work for me, I followed the instructions step by step and it still failed on me.  Maybe a defect?

With the in-depth review someone else gave this, I was expecting ... well, for it to work first of all.  Which it didn't.  I hooked everything up (one HDMI in, two HDMI out to two different TV's [both 1080p], power cord plugged in, etc), and in the end, the output only went to one port.  I tried unhooking and rehooking everything - even had a second set of eyes look at it to ensure I was doing it right - and it still would not split the signal.  Then I tried switching the ports the output cables plug into, and sure enough, the TV I connected to the "working" port came on with no problem and the other did not.  This piece of ... fine engineering ... is being returned!

Failed to work..maybe just a bad one, looking at other options

After hours of Internet searches and firmware downloads, I cannot get this tool to communicate with the laptop. I tried running it on XP and on windows seven with software found on various sites. I have many years of experience with installing firmware and running programs. This is beyond difficult. Perhaps the tool is faulty. I'm returning it.

Some computers won't recognize this and furthermore, some devices won't work when plugged into it.  :-/

I've followed every set of instructions on resetting / calibrating my printer in multiple attempts to make this cartridge work.  The best I can get it to do, is print one copy then the error light goes on.  The print quality of the ONE COPY I'm able to print,  appears to be acceptable, albeit, a bit lighter than the original Brother cartridge, but, I could live with it.  IF it would print more than one page at a time before erroring out.

It takes multiple insertions before it's recognized by my printer, while I can put the Brother cartrdige in, and bam, it's green light and ready to go.  This cartridge appears to fit fine, into it's "cradle, or frame" whatever, but, the printer simply will not recognize it, until after removing and inserting at some random number of attempts it recognizes it and again, will allow me to print one copy and it will then provide an ERROR light.

I've set it to Low Toner continue as recommended by some.  I've pressed the GO button any number of arcane and ritualistic times to no avail.

I have a 2nd one of these, I purchased 2 of course, thinking it was a great deal and being positive I'd be one of the lucky ones who it would work for with no issues.  Not lucky, and issues to spare.

Ok, went ahead and opened the 2nd cartridge this evening.  Was immediately recognized by my printer, no error.  Feeling hopeful i queued a 5 page document that successfully PRINTED ONE PAGE THEN ERRORED, JAMMED MY PRINTER AND CEASED TO FUNCTION.  DO YOURSELF A FAVOR AND SAVE YOUR MONEY.  I certainly wish I had.

I had hoped this would allow connection of an arbitrary collection of "in"s and "out"s.  (3 in, 2 out.)  However it didn't seem to work that way.  (Virtually no signal.)  It seems like this is EITHER a splitter (1 in, 4 out) OR a combiner (4 in, 1 out).  Presumably it would work fine in either of those cases.

I hate giving items a bad review, but I did everything I could to get this thing to work.  First off, I wanted this card because of its robust attributes, ie waterproof, shock-proof, etc. I ended up buying 2 of them and they both failed to work.  The problem I was having was that after copying my music and videos to it, they didn't take.  What I mean is, all the files weren't viewable via my PC.  They just weren't there.  When I checked the properties of the card, it showed the total amount of space that was occupied, around 24GB.  But when I double clicked on the card and selected all of the folders to check the properties, it showed only 7GB occupied.  I checked the folders, and there were missing files.  Some folders were just empty.  I tried different laptops, different sd card adapters, a multi-purpose card reader, but same results.  I ended up sending them back and was able to get a refund for both of them.  Thanks to Amazon, it was no biggy.  I ended up purchasing another card by Gskill and it appears to be working flawlessly.
