I may be mistaken but as far as I know LF is just the filter assembly, no faucet, no tank.

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

I believe it's just an older model number. I haven't found anything with any difference between the two of them.

The only difference between the 2 is that the e5500 comes with Quadpacer which beeps at 30, 60, and 90 seconds to alert you to move to a new quadrant of your mouth. Also the e5500 comes with 2 brush heads instead of one, so you don't have to replace them for a whole year, whereas the e5300 only has one and you will have to buy replacement ones.

They are fundamentally the same, but R stands for retail. It has a few less features and a shorter warranty. Go for the version without the "R and you will get a 5 year warranty and some more useful control features. I bought 2 of this one, but Amazon has it direct for a little less, but they charge tax in CA. http://www.amazon.com/gp/aag/main/ref=olp_merch_name_9?ie=UTF8&asin;=B00G4CIG7M&isAmazonFulfilled;=1&seller;=A2CHZ585KZGNN0

I don't know the difference. All I can say is that the one I bought has been working fine for nearly 3 months now.

I do not know what is the difference between the two. Maybe one is a older verison (AQ-4000)? Hopefully, someone else can answer the question for you and me. ;-)

I did an online chat with Philips support asking this exact question (after being surprised that Google could not help me!).There is no difference between HTL9100 and HTL7180.They are just different model #'s for different regions. The HTL9100 is the UK model, and HTL7180 is the USA model. Apparently any Philips product with a "/F7" at the end of the model number is the USA region's model.

Both work. First is AP mode, the 2nd is "bridge" mode (there is a hardware switch to choose between them)

Hi, thanks for your inquiry. There are only a bit difference between P780 and A830. You can compare their specification in the description for the details. Just buy the one which you like. Have a happy shopping! Best regards,

I think the 83250 is just a newer model. I did not see any difference between them,except for the price. I bought the cheaper one.

The biggest difference is that the XP-557 using springs for resistance where the XP-556 uses elastic cords. The springs provide a more studio-reformer feel. The XP-557 also has more wood and is slightly longer (3.5 inches).

I can not find any difference. I can only assume that the 0865 replaces the 0855

The One is a newer better design in my opinion, but other than design differences the only true functional difference is that the 890 has RF.

Go to apc.com and look at the technical specifications for that model.The manufacturer is always the best source for fiquring out how a product works.

I don't know what the difference is. All I know is that the 6301 only functioned for about 4 weeks. After that they just stopped communicating with each other.
