I received it faster than promised and it performs almost as good as the original.  Well worth the price!

I needed a fast drive to expand the avaialble storage by replacing my OEM 250GB HDD in my MacBook Pro. The drive works great and the 7200rpm speed allows me to quickly edit photos and manage a large photo library. I just followed the instructions on ifixit and after creating an image of the original drive onto the new drive, the actual hardware replacement took less than 15 minutes. The laptop seems faster now that it was with the OEM drive.

This thing makes my computer go leaps and bounds faster than it's OEM 5400 RPM drive. Battery is about the same, but it boots in 15 seconds flat and everything loads, runs, copies much faster.

works great and it was delivered very fast .....doesn't even get hot like my original one does....the only down side is that the power cord is not as long as the original...but i'll give it a 9.5 out of a 10

This is a much improved product over the original and I found it very easy to use and durable.

It is as good as the original, and it's a perfect match for the one I lost on vacation last June

So far it was a great purchase. It lasts almost twice as long on a charge as the original.

Works great. I tried it multiple times and it is faster than the card that I used to use, so now I have a faster card and the original one is my backup.

I bought one two weeks ago for my samsung galaxy s4 because the original charger kept saying, "use original charger for faster charge" or w/e. It was very slow, a trickle if you will. I bought another one for my boyfriend because his was frayed. Both work great certainly faster than our old ones.

Only con is it is a little loose in the outlet and easily becomes unplugged. Not a huge deal, but you can't spread the prongs if you ever want it to fold.

Good replacement part for the money.

It's not the same as the original, but it works just fine.  Reasonable cost and acceptable performance - what else do you need?

I had it's predecessor for over 30 years. It was durable and easier to use than many others  .  I hope for repeat performance.

The only problem we had was  how  SLOW delivery (by Amazon) proved to be.

My boyfriend had recently purchased a gently used Acer Aspire 5532. After wiping most of the extra bells and whistles, it still didn't run as well as it could have- there was lagging when trying to do something as simple as viewing a video on Youtube or multitask several activities. After installing this 4GB kit it seems to be running a lot more smoother, however there are still some blips, I think this is because it's a fairly older laptop. We're upgrading soon, but thanks to the kit this laptop's performance is fine for the time being. Installation was a breeze and it was up and running as soon as I restarted the computer.

I am very happy with this drive.  It is much faster than the original drive that came with my laptop

This renewed performance and longevity of my daughter's scooter. In fact, it's faster than when it was new.

I read the reviews and it was suggested I buy the more exensive brand but I opted for this model.  I've had it in my laptop for over a month and it is performing as good as the original.  I'd buy it again should the need arise.

At first I didn't think this would be nearly as good as the original.  Once I played,  I loved it. It is almost as good as the original.
