Works like new...for a while
596292
I have a new one of these. I wanted to have two devices so I bought a refurbished one. Other than I had to twist the headpiece to make the device fit (didn't have to do this with my new one) it works about the same. What I like: lightweight, can roam 30-50 feet from my iPod or iPad. What could be improved: placement of the volume buttons. When trying to operate, your free fingers can accidentally press the buttons that move your music or book selection forward or back.

Unfortunately both the new one and the refurbished lasted less than a year before becoming defective.

The unit works great and runs as promised (about 6 min on MAX and 15 min on normal). The unit was refurbished. The battery pack was clearly used and abused (it is quite scratched) so I do not know how long its life will be. The housing (the thing that holds the dirt) was quite scratched up but it was thankfully not cracked. Clearly it had been used/returned and was not a slight scratch which I've seen with other refurbished products I've bought in the past. I bought an extra battery just in case but my luck, the extra battery charged and died (it was not a dyson original product but carries a great warrantee). In sum, great product, questionable life on the battery because it appears to really have been used a lot before.

I have bought three of these units over the past two years at this same price from this vendor. The first two were new OEM parts in sealed boxes. The last one I received was refurbished, wrapped in bubble wrap and packing tape. IT STILL HAD OLD SPILLED TONER ON IT from the previous user. If this company cannot even properly clean the old toner off the unit, I do not have much confidence in the quality of the refurbished part. It has been installed for about two weeks now and is working satisfactorily. I am keeping my fingers crossed that it continues to do so.

I had one previously which died about two months in, It took a while to arrive from china, hence no attempt to replace it, this so far has worked fine. and I am pleased.

I've had this surge protector for at least 5 years at this point. I originally purchased it from Circuit City (before they went out of business). It's lasted and done its job throughout multiple moves, countless plugging and unplugging, and years of constant usage. It's saved my devices from numerous power outages, etc.

Just recently though, it stopped working. It was very obvious when it happened as all of my electronics just died and the device now makes a constant high-pitched beep/buzz while it's plugged in. It felt very hot (probably died because it overheated). I'm not sure if it's because I had a small A/C window unit plugged into it or not (it had been for many months).

Either way, the Monster Cable device is now unusable -- so I called the company and they'll be sending me a replacement for free once I send the dead one back. Free of charge...even without my receipt. Trustworthy brand for a good quality device.

I purchased this from "GDreamer." The drive I received works but it is most definitely not new as advertised.  There was obvious wear and tear on the case indicating it is used or refurbished at best.  Unlike my old drive it also makes a loud buzzing noise.  Other than that it works fine.  Installation is somewhat complicated but there are step by step instructions on the internet.  If you follow those and keep track of all the screws and components while you take it apart you shouldn't have any problem.

Update:  It died after 12 months. Hopefully I can find a replacement in better condition than this one.

I purchased and installed this unit in 2004 to replace the one that was installed when my home was new in 1993.  It has worked well all this time, but my wife was looking under the sink and discovered some yukky water spots on the floor of the cabinet.  Further inspection showed a buildup of dried water/scuzz on the side of the disposal.  Cleaned and scraped off the scuzz and revealed a crack in the plastic casing.  I probably could repair the crack with silicon glue, but after reading other reviews mentioning cracked cases, I think it's time to replace, not fix.  So maybe I'm just lucky, but this unit lasted for 11 years with no problems until now.  That's why I gave it four stars.

I'm thinking I will replace with the Insinkerator compact unit.

p.s.  Lots of folks complaining about the lack of a brand new, installed power cord.  What's the issue?  It is stated that it doesn't come with a power cord.  Just remove the cord from your old unit and put it on the new one.  Very easy to do.  Just sayin'

I love this!!  My original (exactly like this one) finally died after about 6 yrs of use. I was tickled when I saw this on line. I received it in a timely manner and it works just like new! I don't know what I'll do when these are no longer found!

It worked really good for like a year and then it started to glitch, but $50 for a year of use is a good deal in my opinion. Therefore, I would recommend to others.

Edited 25 Jan, 2016. See below.

I've had this for a few weeks now. Basic functionality is perfect -- no noticeable effect on charging time/rate. And in fact, this seems more rugged than the original. However, this means it doesn't have the same 'premium' feeling as the original. This doesn't bother me at all, but if you're wondering: the rubberized coating is a bit stiffer, transformer box is matte instead of gloss plastic. Also, the charging light is dimmer and (very) occasionally doesn't turn on unless you unplug/plug the connector. There is also one extra light on this part: the AC/DC converter box has a dim green LED on it that lets you know if the charger is plugged into the wall.

The brick isn't noticeably hotter/cooler than the OEM brick as far as I can tell. Also, the brick seems a bit lighter than the original. I won't speculate as to why that would be.

Overall, this product is cheaper than the OEM part and has performed extremely well so far. Unless you really like a premium finish, or are concerned about letting anything non-Apple touch your computer, I'd recommend this product.

Edit - 25 Jan 2016
Charger stopped working today, about 6/7 months after purchase. Have noticed that recently, the little orange/green LED on the magnetic connector wasn't coming on. Today, my computer reported "plugged in, not charging" -- it could tell the charger was connected, but was not charging. I tried everything I could think of (plugging into other outlets, trying another charger, resetting computer settings) and it seemed that the charger was the only thing not working.

So, thinking my unit was dead, I cracked open the case and took a look inside. I could see nothing obviously wrong -- no blown capacitors, for instance. And obviously the unit was supplying something to my laptop, since it could tell whether the charger was connected to the wall. So, I'm not sure what's up. But, having (literally) cracked the thing open I can't put it back together to try using it again.

However, considering that my original Apple charger only lasted me a year, and this one lasted six months at a third the price... I don't feel that this product was a bad deal. To replace it, I'm probably going to get another OEM Apple charger, since the problem I had with that one was the cord fraying, and I think I can prevent that now that I know about it in advance.

Like new but you can tell it won't last a long time, seems like weak material, But its worth the money for the refurbished one
