Summary: This Mp3 Cd Player Is Awesome
Review: This baby rules, I got it for my birthday and it is awesome!.
The Navigation is incredible, The LCD is readable (even without a backlight), and it come in a cool blue case.
But there is a dark side,
One day I tried turning it on and nothing worked: new batteries, waiting 5 five minutes;
5 minutes later I finally realized the hold switch was on. When you press a button on my old CD player while it is on hold, It shows the word "hold" on the screen. The RioVolt doesn't but you can adjust.The Screen is readable and a backlight is even needed. One Last thing
GO CARDINALS!

Summary: Excellent Product
Review: I purchased this on Amazon, picked it up at Circuit City the same day, went home and burned a cd with 170 MP3's before I could manage to get it out of the annoying plastic retail packaging. It played very well, so I converted 310 MP3's to WMA's and burned them to a cd. It still played perfectly. For 5 days of traveling around Thanksgiving, I only brought one cd, set on shuffle. I was very nervous about making this purchase after reading all the reviews, but I'm glad I settled on this brand. I have been buying their products for many years, and have always been happy with them. I wish the buttons were better configured for making changes without looking (like while driving). Ex: The four feature buttons on the left are too flat and it's difficult to tell if you've actually pushed them. With the multifunction button, I am constantly pausing or stopping the playback instead of jumping to the next song. The initial startup time makes that annoying, and you lose your settings, such as shuffle all, forcing you to hit the mode button 8 times to reset it. It's still all I was expecting and more, though.

Summary: Get ready for a new approach to portable music
Review: It was difficult at first to prepare a cd-rw the SP90 would successfully play. You need to record the tunes at 128 kbs in mp3 or wma format using 1X sampling. Keep all the tunes on your computer until you are ready to burn the CD-RW or CD-R. Burn it in one session at 1 or 2X, not a faster rate. The SP90 will only index what's on the disk from the disk's first session. If you use wma format, you can put about 20 hours of music on one disk, and the player will only have to spin the disk intermitently to play the tumes. You should expect battery life of over 10 hours. Sound quality is excellent. When you get used to how to make disks for it, this machine is a bargain compared to players that use a hard drive. The Rio website is poor at providing access to the purchase of a carrying case or AC adapter. Except for the tedium of preparing a compressed disk for it, this machine leads the way to what we want: a lot of music in a small space.

Summary: Great for under $100
Review: I held off buying a sub-$100 MP3 player because they lacked basic navigation and display features. This one nicely displays your ID3 tags as well as makes it easy to navigate through directories on your CDs. This is very helpful! The first unit I received had to be returned, but the second one is working like a charm. Amazon made exchanging it very simple. The lack of backlight is bad if you are going to use it at night, and not being able to update the firmware means no support for new technologies. But probably by that time you'll want a new one anyway... My suggestion -- buy it, it's a good deal.

Summary: Power hungry fickle malconstructed player is not worth $
Review: First off the thing has a battery life of about 4-6 hours. Ok I thought I'll use the power adapter... doesn't work, just doesnt work.
The skipping: I did the tap test and yes it did skip, was there a switch on the bottom as advertised for ESP? no! the manual says there is, but there isn't, it's utter bull. Don't waste your monmey or your time, my friend has the same player and same problems.

Summary: Sweet
Review: I too had trouble with skipping at first, but as long as you burn it at a slower speed while not running utilities it wont skip at all. I made a cd with over 17 hours of music on it and it hasn't skipped once. I love this and all my friends are really jealous. I'd say get this and forget the backlight, it saves u 50 bucks for a couple features.

Summary: It works, it looks nice
Review: It works as described, package included 2 AA batteries, 1 set of earbud, SP90 and a piece of document. Most sub-100 MP3-CD players I've found at local BB and CC looks really cheap, this one does not. It also looks thinner. The rubber surface looks durable. The earbud could be better. One nice thing to find is that when playing MP3s, the CD spin a couple of seconds, feed the data to the buffer, and it stops spinning and play through the buffer. That way it saves both the batteries and the skipping. Actually I think it looks better than its flashy bigger brother, the SP100, also thinner. I really liked the low-profile looking, though I will like to see more color options. Lacking the rom-update-capability really does not bother me. Hey, it's not some M?cro?oft that needs repeated update for bug-fixes. Back-lit is not neccessary since most of the time the piece is sitting somewhere other than my hands, I can not see the LCD screen anyway. Case and LCD remote will be nice, but I won't say that plus the FM radio will justify the price difference between this one and SP250, but the 8Min buffer will be really really nice. The only reason I did not rate it as 5 is I don't have a long-time experience with it. Will revise later.

Summary: Excellent for what it is...
Review: ...which is an inexpensive MP3-CDR(W) player. I've had my SP90 for almost a month as a substitute for a car cd changer while I'm scootin' about in an insurance rental (not my fault, so there! <g>). Anyway, between commutes to/from the office and a couple of trips out of town, I've only had one nit to pick with the SP90. Depending on the type of music burned onto disc, the player does have tendency to take a couple of seconds longer between tracks, so the car tape deck's auto seek goes gonzo. I suppose an upgraded firmware could possibly address this, which is all pretty moot, as the SP90 is about as upgradable as a brick. However, until I've seen for myself that SonicBlue has come up with a Rio Volt firmware that pre-emptively reads ahead to the next track and eliminiates all between-track gap, I'm not going to lose any sleep over this feature, or lack there of (but then, even the solid state players have a wee bit of a gap between tracks, so there!). I've also taken the SP90 on a couple of out of town trips, and having the ability to take so many tunes in such small space with such long battery life (about 8+ hours of MP3-CDR's and regular audio CD's on a single pair of alkalines) is quite nice. Not being limited to the same 64Mb (or marginally more) of solid state player content (or you'd have to lug along a laptop to change out tunes) or taking a large stack of minidiscs is a real convenience, considering the current one bag carry-on restriction on planes. The anti-skip for MP3 content is quite good, as I was able to listen to glitchless music while making the rounds in San Francisco on foot, on bus, and on cablecar. The audio CD playback is a bit iffy, but that's really not the reason I bought this thing in the first place. Not having a remote is a bit of a drag, and haven't even bothered with the included headphones (but the I haven't bothered with bundled headphones on any Rio product since the Rio500). But what do you expect for the low-end model? So, as much as folks may mourn the lack of upgradeability on the SP90 as well as the lack of some other niceties, it's definitely a better model than some of the other low-end MP3-CDR(W) portables out there. And it definitely meets my requirements well enough.

Summary: rights wrongs pros and cons
Review: after owning it for a week it probly wont skip that much but then it will skip alot but usualy not if you hold it in your hand and sometimes it will be okay in your pocket. i have owned mine since august now its broken even though i have dropped it my fair share of times. but it is a great thing not many mp3 products work with wma and if you own wma files you dont want to spend all day looking for a free wma>mp3 program and then convert them this you just slap on your mp3 and wma files all mixed up on here and it works like a charm plus you can use RW-CDs and just change the songs whenever you want plus the cds are usualy 700mb of space and mp3s are usualy 2 - 4mb a pop so you can store a lot on there despite how soon this broke im going to purchase it again now its even cheaper. oh another bad thing about this is taking an hour to explain how it works when people ask you about just tell them you wrote mp3 on there for the heck of it and its a cd player.

Summary: RioVolt review
Review: This Player skips when playing audio CD's. It doesn't have near the 40 sec anti-skip protection it claims. I can not play CDs while walking with it in my bookbag. It skips too often (about every 5 secs).
