Worth it even if you only make one repair.

I found this item to be a "must have" when replacing the screen on my iPhone 4s.
It replaces the paper step-by-step flowchart with a nice flat surface that has a place for every tiny screw and part.

Just what I needed to repair my speakers. Easy to repair as long as you take your time

This item was a very satisfactory replacement for the broken digitizer to
my 3GS.  One should be handy with small tools and fine work to attempt
the repair, however.  You don't have to be a jeweler by trade, but be prepared
to mate and demate the tiniest screws you have ever seen.
I would have given it more stars if it came with clear instructions, but
Youtube has what you need.  However, the youtubes I watched didn't
give me adequate caution how delicate the LCD screen was that you
have to separate.  I busted mine in the process and had to do another
repair of that with a non-OEM substandard replacement.  For a backup
phone/now iPod, it was a cheap way to get it back working again.

This rebuild kit is a must try if you aren't able to keep your portable dishwasher hooked up while you try and use it. I was given free an 8 year old dishwasher, because the owners didn't want to fix this part. They just went ahead and bought a new one. It was perfect, except the sink mechanism didn't stay attached. This part, and ten minutes of work (because I was doing it slow to show my cousin who I gave the dishwasher to how to fix it) netted us a dishwasher that will last a few more good solid years. General note, when detaching and attaching this to the sink, you should pull down on the release collar. It will help preserve the teeth.

When the top rack of my Kenmore Elite dishwasher broke, I gritted my teeth and prepared to call Sears repair. But then I found this and easily fixed it myself. I say "easily," but I confess that on my first try I had everything hooked up backwards. Duh. Once I fixed that, it worked like a charm. As others have said, the printed instructions that come with this are laughably unusable, but there are numerous excellent YouTube videos that got me through it, though I should have paid slightly closer attention.

Great and cheap fix for a major problem, good tutorial over the internet. Is not hard to do it yourself if you can follow directions.

Perfect fix, very easy to do with few tools needed. Saved tons of cash fixing my controller versus paying  $60 for a new one. I wish it came with new joystick covers and I would pay extra for it!

Easy to work with. Great for tough repair jobs. Part of the dash board plastic mounting tabs broke off. I reformed the tabs with apoxie sculpt. Reinstalled the broken part and it is better than new.

When something is this easy to repair it's silly to pay a repairmain a pile of.money.  Just think, all the money you save can go towards your next Amazon order!

Saved hundreds repairing this myself. Have not had any issues yet.

Easy to replace (if you find the correct directions for your model)
Works like new again, fixed it myself for 1/10 of what repairman wanted

This replacement part worked perfectly for me. Please be advised however, that this is a very difficult repair regardless of your electronics savvy.
Because the power/volume/mute ribbon cable was located underneath the area where the digitizer glass was shattered, I was  unable to salvage it, even being cognizant of its presence.

Things to consider

1.) Pay very close attention to how the previous cable was routed. Take pictures beforehand. Take pictures noting how the cable is attached to the metal brackets as well. You will be pretty confused if you don't. I took pictures and was still a little bit confused.

2.) When disassembling, take pains to make sure you keep track of all the microscopic screws and where they go. I taped all the screws to a piece of paper with written notes. I would really recommend a magnetic driver. I'm not sure I would have been able to do the repair without one.

3.) The sticky contacts are not that sticky; the rigidity of the cable makes the contacts peel off the brackets when you are trying to route it. Because of this, you have to route the cable nearly perfectly so that you can force the actuator and switches into the right spots, since they won't stick on their own.

4/5 stars because of the lack of stick on the contacts

5 minute fix and it worked perfectly.  May order another one just to be ready when this one wears out.

For a couple dollars I repaired our blender giving it a new lease on life. Came off with a little persuasion not too hard at all.

My daughter cracked her screen on her Chomebook 2. After the rather pointless call to Toshiba, while on hold for repair I stumbled upon this fix and figured it was worth a shot. This repair was unbelievable easy -  it took me right around 15 min. I had no training other than a ytube video. 2 days later her screen went black and I opened it to find the plug had come loose. Fixed it with a bit of tape and everything is fine again. If computer companies continue to make cheap items, it helps to have an equally cheap and easy fix. I'm glad this worked for us.

This was fairly easy to replace.  I have very limited knowledge of plumbing, and I was a little intimidated by the idea of tearing apart my shower handle when there is no way to turn off the water other than turning it off for the entire house.  I proceeded with trepidation and was able to make the repair in under ten minutes.  It took just as long to gather the three tools I needed and turn off the water as it did to make the repair.  The replacement part, although slightly different from my existing part, slid in perfectly and worked on first try.  The instructions that come with the part were not all that easy to understand, and the print was so small I could barely read it anyway.  I watched a Delta repair video that I located on YouTube and it was much easier follow.
