What is the basic difference between the S1 and S2? I see the speed ranges are different but that doesn't seem to account for the price difference.

I believe the main difference is the battery in the S1 which allows you to use it without a cord. However, I have found the battery life to be short- I still need to carry the plug with me to work; I seem to be able to pump only once per charge.

The S1 is (rechargeable) battery operated, that makes a major difference. I love the S1, it's worth the money, and then some.

I have the S1 and it does not need to be plugged in to the wall to run. As long as it is charged, it can be used anywhere without the adapter. I believe the S2 has to be plugged in. I'm not sure if it will run on batteries.

I actually have the S1 and the S2, they are basically the same pump, except the S1 is rechargeable, (and blue) while the S2 MUST be plugged in to work, it does not have a battery of any sort (and it's pink). I LOVE both pumps! but the S1 is definitely worth the extra $$ for the freedom from the plug! I find I can get about 3 1/2- to 4 full pumping sessions out of my S1 before recharging!

I believe the major difference is the S1 has a battery so you can use it without plugging in.

Hi, honestly I've never had a S2 before so I can't answer your question. Sorry for not being helpful.

Yeah, Amazon's got this info really messed up...I can't figure out what the difference is between this model and one $40 cheaper, as apparently they're both Atoms with 2GB and 64GB storage. The price difference would make sense if one of them had more storage (or SOMETHING), but I can't figure out what the difference is.

Strangely, I've noticed no difference in transfer speeds between them. To me that means that the smaller buffer isn't the weakest link in the transfer.They also removed the blue circular status light from the front of the drive and now it lights up by the USB port.Both 5200 RPM as far as I know. I think the Elite has the slightly faster drives and more buffer size.

They look the same, but inside have some differencies: S50 Bluray, 4GB RAM, 500 Hard Disk, Win 7 and is more expensive than S55. I recommend S55; a relevant difference I see is the bluray player and that isn't more important than the processor or the hard disk.

I had the same question. Given the answer, it appears the s version is better(?)

In my experience they have about the same range. They both use the same motor and battery. The only difference is that the SS motor is factory set to run up to 28 mph. If you were to put both bikes on a flat surface and run them at max you would go a few miles further with the SS. But rarely do you run at full throttle all the time when riding normally. Kind Regards Jack

The s1 use a system with a rubber to make pressure and the deluxe use a more durable wheel. The Deluxe is made of stainless steel. Deluxe is a better product.

S2 and s2 skyrocket are 2 completely different models. This is for the standard att galaxy s2, not the skyrocket version

The s2 has a charging circuit that will regulate the current to the amount it needs. It would only charge faster in the 2.4 amp port if it needs more than 1 amp. The internal s2 charging circuit will keep it from overheating in either port.

Here is a great link that should answer your question:http://www.golfgps1.com/Garmin-Approach-S2-vs-S3-Difference-Between-Review.html

I didn't notice a difference. The speed controller kind of seemed pointless. There's only 2 settings low and high. Low is nice and high for me was just too much!!! So I only use it on low haha. I hope I answered your question.

I couldn't see any hardware difference. Externally they are virtually identical. I had a previous version that broke. That's why I was able to physically compare the two. However, the newer model comes with a new software that the older one will not get upgraded to. The new software does the same thing that the old software did with the exception of a new Android mirroring thing. If you have a modern smart phone, such as Samsung Galaxy S3 or newer, you can show in your TV exactly what is in your phone screen. I don't think it would be worth buying a newer version just for this feature but, if you are buying a new device, you should get the newest version to be sure to get the latest software updates.

The unit is great, no updates for the s2, the s3 is out also, firmware are the same with sine diferent values due to diferent components in the units, but codes still the same, to really get full potential out the s2/s3 cord is required to prevent the minisleep mode to protect battery, that's a trade of for the ugly cord on your dash.

I don't know the difference between the two--only that one is a newer model than the other. You should research the model numbers.

Warren, I cannot decipher any difference between the 2 models listed. I think they are one in the same. That said, if the merchant told you that it is better than its predecessor, that may indeed be true--if he is comparing it the 61/71 series or the 65 series from last year's model line. But even Samsung's website doesn't mention the S2F being any sort of an upgrade or anything like that. I've been looking at the A860 for a while. The slim depth plus its couple extra features make it a bit more attractive than the 6 or 7 series lines.

The only difference I see is that the pro offers two speeds while the personal offers one. I've been using the personal for a few months now and love it. But never having seen or used the pro, I can't say on that.
