What is the difference between this M570 and the model that is $5 less?
355738
I would guess the size and design? I purchased the M570 because it seemed more suitable for my issue with my right hand. I would just look under the description tab on each to see the differences.

Looking over both ads, they are the same product, just different pricing. AS for the M570 itself, this last order was the 3rd of the same model over the last several years. Mine is used quite extensively and the battery life is remarkable, performance is flawless and just an all-around pleasure to use. Over time, they fall on occasion onto my tile floors so they wear out just from being manhandled. But I keep ordering the same for it works so well.

I like that the ball is on the side and it is wireless. They are the same thing ( make and model ) from what I saw.

I'm pretty sure they are both the same, just from two different vendors. I've had mine for quite a while and love it!

I really don't know what other model you mean. I wore one of these out (after many, many hours of clicking) and so I'm on my second one. And Love It. The batteries last forever. It has a couple of features that I'm sure would be handy to a more sophisticated computer user. I pop out the trackball every month or so and run a microfiber cloth over the contacts, etc.Otherwise it gets a little hard to move the cursor across the screen smoothly.

I don't think there is any difference there. But my suggestin don't buy either. Better buy 798H secura. It's way better plus it's self cleaning. I got 997MC and I am tired of cleaning Regret regret and regret that I got it.

I don't know, I haven't used an m570. Hows that for honesty?, however I was informed that a wired mouse is better than a wireless mouse because there is a slight lag time between the transmitter and receiver in the wireless version. (not so good for gaming apparently.) That's why I chose a wired mouse. As far as the price is concerned, I doubt its a typo, wireless technology is more advanced than wired and so you are paying for the tech. Think of it this way: a land line phone is wired and you can pick up a decent phone for around 30 bucks at Walmart. now compare that to the cost of a cellphone which is wireless.

If you really want a smiley face looking at you first thing in the morning, get the 5000. As far as I can tell from the comparison charts, there are no real differences between the 5000 (which I own), the 3000 and the 4000. RPMs, and battery lights are the same. Each toothbrush breaks up the two minute brushing cycle into 30 second periods, so you don't really need the count-down feature (?). IMHO, these are meaningless add-ons intended to increase the price without increasing the value

currently (Aug 2011), if you buy the 5300 + 2 replacement heads, for a total of 3 heads, it comes to a few dollars *less* than the e5500.

I cannot speak to the difference as I have the 612 model. I love it and have no complaints about it whatsoever. I highly recommend it. Sorry I cannot speak to the difference for you

Hey there! I'm in the same predicament also? I just purchased the 32m3000 series for the "cheap" price of $649 when it was available at other non competitor retailers for $550-575. (I wanted the 4 year protection plan the cheaper guys didn't offer). It's a gift for father so it's not opened yet. The only thing the store assistant said was that one model's from 2007 and the other is 2008. He didn't want to lie to me about tech knowledge he didn't know about.

From what I can see there is no substantial difference between the two series. They look the same and have substantially the same hardware. The M5 listings I have seen seem identical to the V5 I bought. I recommend the V5 so I can imagine the M5 is good too. One note: I got the V5-573PG-9610 which comes with an Nvidia GPU. If you can find this, it is worth it! It makes games and video and graphic programs run much better.

The difference is the M525 is a laser mouse. I think the M325 is an optical mouse. The M525 will work on almost all surfaces.

As far as my research went... The cheaper one could be an older model, refurbished or an open box item (meaning it was returned).

I wonder why the less expensive one is less expensive...are the differences in feel, materials, quality and/or size?

Not sure since I only have the 550 model. But I imagine not a big difference. 550 is very durable

I don't know if there is a diference between models. I have it since 2012 and works great. Sorry!!

The weight of 2AAs in the M505 makes a difference compared to the M305. What I like most about the M305 is that it has only 1AA battery and so it's very light, easy to move on many surfaces because it doesn't have as much friction due to its low weight.

The primary difference is this model does not have any built in memory and requires a memory card. The M has onboard

One more difference between M305 and M505 is that M305 is optical, with visible red light, and M305 is Laser, no visible light. Also, the M505 is a tad bigger than M305. Not by much, I will say about 0.25 inch longer, but same width.

Not sure it you have purchased the product already. Wanted to replay as the 500s are on 'Today's deal' and the difference is 30 now. hope you get email for this reply. I compared both the system when I bought them year ago and chose 500. The difference was not 200 for me in a local electronics store. If you listen to lot of music, I guess the difference is justified.
