Summary: Bad Product, Worse Tech Support!
Review: I purchased this product. It worked great for 2 weeks then started flashing USB. Nothing would play and unit would not even turn off! I have been talking with tech support for 2 months now, they gave me horrible directions for fixing it, it only make the problem worse and/or corrupted some files on my PC so that I had to delete/reinstall everything (I am A+ Computer Certified, so yes, I know what I'm doing). Each email to tech support takes at least 5-7 days to respond. My unit was sent back over a month ago and I still do not have a replacement (They make you pay for shipping charges for the new unit as well!) I would not recommend this product based on other reviews as well as my own experiences with their tech support. One plus, the included headphones have a great sound to them.

Summary: good sound, bad display
Review: I just purchased this at a local electronics store. A great price after the rebate but I am returning it because the LCD display is pretty much useless. An MP3 player should show the title of a song and artist (it's the whole point of having MP3 after the compression capabilities), this one just list the track number. So I guess you have to memorize the song title to it's corresponding number. The sound is actually good. THis is my second MP3 player and it beats my D-Link in sound quality. The RIO one is cheaply made, the D-Link is sturdier. I would keep if the LCD display provider more info.

Summary: A Worthless Piece of Plastic
Review: My Rio One was fine when it worked, but then it stopped working and I was faced with the SonicBlue support department. After about a month and a half of waiting several days for each Email from the support department, the support department determined what had been painfully obvious from the beginning of the matter: the Rio didn't work. Now, I am in the midst of a three-week battle for the privelege of paying Sonicblue [$$$] so that they'll replace my broken player in a reasonable amount of time (As in, reasonable amount of time after close to a month of waiting for them to get their act together). Furthermore, they've just informed me that it will be necessary to charge the full amount to my credit card before they send me a new player. This company's actions make it clear that they have no interest in satisfied customers. I am left with a worthless player, a worthless SmartMedia card that I purchased for it, and months of hassle trying to get a clearly defective product replaced. I suggest that anyone interested in this player look instead for a company that has customer service at a level somewhere above "non-existent."

Summary: Good Basic MP3 Player
Review: All things considered this is nice basic MP3 player.
It is relativley inexpensive, easy to use and light weight.
It is not perfect. It looks and feels like it was cheaply made. I am afraid if I drop it that will be the end of it.
Sound Quality is not so good. Not even close to cd quality. Sounds more like a cheap walkman cassete player.
But the low cost and portability of the unit make it perfect for working out or listening on the beach.

Summary: Mine died a slow death...
Review: Ok, I bought this product and it was working fine for a while as long as I was only playing run-a-tha-mill basic MP3z. The WMA experience was somewhat less consistant, with some tracks not playing all together, after a certain point. I could not ascertain if it was the encoding of the particular files or the player that was the issue. The player worked fine with a 128 mb smart media card I bought also, until one day it couldn't boot with the card anymore, but booted without it. Tech support told me to go try out the card in another player, suggesting I go to a store and use one of their units to test my memory. Yeah right. Their lack of good advice forced me to figure the problem out myself, performing a tricky operation of loading firmware without the card, then putting it in, then unplugging it from my computer and letting the firmware re-formatt the card. It worked for about another month. Now it will not boot at all, with or without a memory card! I bought this product to be durable. I bought it to take my music with me. Now it reminds me of a Dodge truck because it is really "like a rock." Buyer beware! I know the price is enticing. I know it looks good. However, YOU PAY FOR WHAT YOU GET! YOU DON'T WANT A PET ROCK! YOU WANT AN MP3 PLAYER! GO GET A JOB AND SPEND YOUR [MONEY] ON A REAL PLAYER!!! Check out some of Rio's other stuff, or just shop around but avoid this ONE.

Summary: works great(if you know what your doing)
Review: I got this mp3player off windows xp and it works great! Here are some pros and cons about this player. pros: resonable price, good sound, largly expandable(up to 160mb), very low wieght, small size, more than 5hours to ONE good battery, and the EQ modes, random and repeat modes give it more than enough options. cons:casing on the sides of the mp3player are partly lose, screen is very primative, the memory cards it uses are small and thin and can be broken if not handled carfuly, the battery cover is wiggly, and the head phones that come with it aren't that good.
But over all what do you expect not every things going to be purfect on a hundred dallar mp3player. I say this mp3player is good and I do suggest it.

Summary: Where did the external memory go?
Review: I disliked more than less of the Rio One. Extended memory has stopped working although I've reloaded the flash many times and gone through the www drill of locating potential answers. Instruction book is over simplistic and not addressing potential problems very well. Help desk is past my waiting time. Good Concept, would not recommend it to anyone. P.S. "Cash back" voucher was returned after 3 months stating "bill" was not submitted. Not! Amazon.Com should regulate companies like this or at least stop selling defective products.

Summary: THE BEST MP3 PLAYER I HAVE EVER OWNED!!
Review: Before purchasing this MP3 Player, I read the reviews by other owners and how the player deserves one and only one star. Well, I purchased the player at my own risk and have since been extremely satisfied with it. I am writing this review to counter all negative statements against the Rio One. Many of the reviews stated that they received the Rio One free with the purchase of Windows XP. Those who did not purchase items directly from Amazon.com or such retailers should not be complaining about it. The buzzing sounds, blips and static is something that I have never encountered on my Rio One. It has never stopped playing nor has it failed me in any way. The Rio One to this day continues to function perfectly. Its hard plastic shell is the reason for the player being lightweight and portable. If you are looking for a decent MP3 Player at a reasonable price from a renowned company - the Rio One is for you. Unlike those buyers who purchase the fancy/bulky/multi-function MP3 Players that costs up to $200, I say why invest so much money!?! THIS MP3 PLAYER IS WORTH EVERY PENNY YOU SPEND AND IS NOT WHAT MANY OTHERS HAVE STATED IT AS.

Summary: Decent product
Review: I used to own the original Rio Diamond 300 and it worked beautifully until for some odd reason it stopped working (my guess it would've been the cold temperature at the time). Anyway so I needed a new one to replace it and since Rio One is basically the exact same model as the old one, I bought it. Personally, I find my Rio One works like it should except for one fatal flaw that [really bothers me]. Whether it's an MP3 or WMA files, if the file itself is not a flawless rip of the song, my MP3 skips during the song. It would actually go into skim mode and fast forward and resume wherever it stopped skimming. Apparently, I don't think anything can fix this unless I keep searching for that same song and try to download it on my MP3 and play it to see if it works, but that's too much time consuming. So, it's either you have the whole song or you don't. That's the only thing I don't like about it, but other than that it works great. This MP3 is made to be clipped on your pant or stored in a pocket, not to be held in your hand, it's no surprise that you're gunna drop it eventually. If you're considering to buy this product, buy it at your own risk, but I think it's cheap enough for the amount of memory it can hold (up to 160 MB). I'm not fond of small earplugs, but buying larger headphones should be no more than 8 dollars. Be sure to read the product info on the Rio website so you're sure this is the product you want. Yes it's very light, yes it could break if you're going to drop it, but that's your own fault if you can't take care of it. I find it pretty practical, listen to music whenever you want, wherever you want all for 1 AA battery for up to several hours!

Summary: Great player, execllent sound, low price
Review: This is the best MP3 player I ever heard! This player sounds great, has roomy storage space, and has fast transfer time from computer to the Rio One. The only problem I had was that I at first could not get the Rio software to work right until I downloaded a updated .dll file from their website, but from there on everything went smoothly. For the low price, great sound and quality, and ease of use, I give this 5 stars.
