Does this thing do anything at all?

I can't hear much difference with or without this. No big discernible effect. Not sure what it should do. Anyway, maybe it can make the sound louder, but no richer sound that I can hear. I'm using this on a 2011 17" Macbook Pro, Grado SR325 headphone.  (The headphone is not great BTW, my old Sennheiser was better but unfortunately it broke apart because it's extreme light weight and fragile).

I compare the sound between the laptop output vs. from this Fubar with the same headphone. Must I buy new Opamp and power supply to hear better sound? If this is the case, why don't they just make this thing with those components to begin with?

This thing has never really worked.  I thought it was own settings, or I did something wrong.  But no.  The internet is filled with people having the same issues.  Junk

Purchased this to give the drive some protection.  Now that I have it, don't believe it accomplishes anything.  Wouldn't advise you to invest in this accessory.

Im not sure how you would rate this! I guess it works.... I watched a YouTube that said it doesn't make a difference! So; who knows?

My sister has one of these and she had nothing but great things to say about it. Once I watched as she used it and it worked like magic. So I decided to buy one for myself (a refurbished item). Maybe it was previously misused because the one I got was absolutely useless, although it didn't appear to be damaged. I'm including a photo to show the results of my first and only use of this item, since I'm returning it.

This did nothing. I tried to use this simply to remove a wheel cap. A newborn baby could have pulled this 'remover' off the car. It does not hold any type of suction. Stay clear away from this.

I have no idea if it is doing anything or not. It does not let me know if is removing anything or not.  G. Davis

didn't notice any difference, way overpriced to be so useless.

Pointless. I could not this program to do anything that it states.  After loading I tried to sync but that didn't work.  Even worse it doesn't save any information, it erases data after you close it. I will keep using Google until I find an adequate solution.

Piece of crap.  I never wrote a review before but I feel compelled.  Completely useless for what it says it does.  Compass?  LOL.  Magnifying Lens?  For an ant?  Maybe.  Screwdriver?  LOL.  Only for screws that can not be seen by the useless magnifying lens.  Knife?  About the only thing you can do with this is hurt yourself.  And even for that you would really have to try.

Does absolutely nothing. Waste of money. Thought it was going to restore my leather couch, like the description, applied several coats like the directs stated (if necessary).... no difference...

It was supposed to do all the things my old grinder did and more.  I took it out of the box and ........... nothing.  It didn't ever work, period.  Very disappointing.  Is there a rating lower than one star.  If there was, I would use it.

This product is useless.

This thing does not work at all. If you buy this, you are throwing your money

This thing does absolutely nothing to increase my capacity to receive signals.  It does, however, have a nice blinking blue light which gives the appearance that it is working.

I can't say that it does anything except as a night light. The on/off is just a brush of your fingers over the round 'button' and to dim, it just takes a bit more pressure. It seems nicely made I just don't know about the properties it is suppose to offer.
