what advantage is the newer model?

The newer model is actually cheaper for some unknown reason. As far as I can tell that is the only difference since USB 3.0 is backwards compatable with USB 2.0 ports.

The previous model is a bit more difficult to clean. The Open-Access lid flips out for better cleaning access. I say get the newer one.

I don't know anything about the older version so I can't help you, sorry. New is good?

The main difference between the two is the bluetooth. They use the lastest bluetooth compared to the previous model.

The Ultimate is the newest version. It is designed well and seems to be a bit of an upgrade. Get the Ultimate, it is rock-solid and a real bargain.

I would get the latest version that you can get. It probably not wort the hassle for the few dollars difference between the ʻOld Version" and newer versions. Any way, itʻs an excellent product and has saved my sanity several times and actually saved me money on repairs, without any hassles.

I dont know what are the new features. I love mine. Except that it is a little bit heavy.

I am sorry I don't know. My husbands is a new one and I don't know anyone with an earlier model.

Can't truly answer that question, because I think the Advantage II replaced Advantage some time back. I know some years ago I did use Advantage and then it changed to II. My guess would be this is the new improved version of the product.

In addition to a bit of a difference in sound (though that difference is often overstate, in my opinion), the newer model is also more efficient and will be driven more easily by weaker amps.

Im not sure what the difference is . I have the newest one and it works great. The only problem i had was reading the instructions, they ar written in broken English and don't make much sense. If you buy one and need help learning how to use it you can email me about it. Landrithjames54@gmail.com

I recall when I bought my 9001 a newer version was also available. The newer one didn't seem to be any better than mine other than it was a slightly better looking unit. I don't remember other details other than aesthetics. I love my 9001.

I've had both. The newer model is more sturdy, heavier duty plastic parts, in general, a real improvement. Works the same, but I think it will last longer, I've had mine about a year now.

I have no experince with the previous unit, but if it helps, Ive been using the newer model for over a month am am very satisfied with its performance.

The 990 is the newer model. As far as I can tell, there really isn't any difference except the price.

I believe the old style gives a faster shave, but it is possible to cut your skin easier. The newer screen slows me down some and I get a few more ingrown hairs. L

Bob....I have no idea ! There are so many models out now that I have not been able to figure out which is the newest ! I do know however, that is as good as you can get. I have one and it does everything I want and need !
