what is the difference between U4929 and U4920?

Both have the same features, but 4920 also allows you to mount a hand held showerhead in addition to a regular showerhead .Instead of having to mount the hand held on the shower wall

I don't know the difference-but I had the H730 before and liked it so I ordered another one.

I'm sorry, I am not sure but I believe the U21B is 3200RPM and this one is 3000RPM. I do not think they are interchangeable but if you know the model number you can do a cross check on Fasco's website.

There are several differences. The 9930 has a larger outer enclosure, which might imply additional sound insulation (or it might just be a larger outer enclosure). The 9930 has a 5 year warranty, and the 9920 has a 2 year warranty. The 9930 has a stainless steel grind ring, and the 9920 has a heavy-duty steel grind ring. All of this is from the wasteking.com site.

There are two different part numbers, G57031 for the right side and GS7030 for the left side

I wish I had realized that there was a difference between the two before I ordered 3 packs of the TEN3428-G10's. It turns out that I needed the other ones, so am now having to deal with a return/refund/reorder. The TEN3428-G10 is called a "Surface Mount" and the TEN3429-G10 is a "Traditional Face Mount", but somebody that actually understands the difference would have to explain it to both of us, LOL. Sorry I couldn't be more helpful, but I can say that if I had looked closer at the pictures, I would have been able to compare to the hinges I was replacing, and ordered the right ones to begin with...

Frankly when I google it they seem to be interchangeable. sometimes it is called S-516 and at times it looks like it is called a 516. Sorry I couldn't be of more help.

i don't think there is any difference between the numbers. the "U" on the end is primarily a region indicator (JP for japan, USM, U, US, and so forth). the primary difference may be the information sticker or imprint on the battery itself. the charger does work for both of these rather well.

The 920 uses a compression called H264 which in part of the webcam itself while the C910 does not compress but rather allows the CPU to do all the work. The result is the C910 puts a heavy load on the CPU while being used (this would only impact you if you're using an older computer that isn't QuadCore or similar). The C920 is supposedly capable of 1080p while the C910 is capable of 720p. Both models have Right Light. The last difference is the C910 uses 5 megapixels while the C920 uses 3 megapixels. Both work great so it's really a matter of personal preference and maybe cost. Hope that helps.

the 8620 has 1 paper tray, the 8630 has two the 8620 includes 1 set of starter ink cartridges, the 8630 has two the 8620 has no OCR software, the 8630 includes IRISscan 14 OCR software

When I got 8620, I checked the information decal inside both 8600 and 8920; both indicate the same 950 or 951 ink cartridges; I also compared cartridges from both and they are of the same exact configuration case. 8620 appears to be a slight upgrade of the original 8600.

The TH9320 is the Pro-Install one. It has a 5yr warranty and is white, the RTH9580 is the Retail model (R). It has a 1yr warranty and is grey/metallic. They both store settings in perm memory in case of power outage and are otherwise the same.

When I searched the first part number, I came up with both numbers on amazon.com; the last one was about 3 times as much. I think that they are interchangeable.Sincerely, Wiley Henson

Apparently the 16GB and 128GB cards are U1. The 32 and 64's are U3.As you may already have discovered, Amazon commonly mixes descriptions of products that are basically the same brand and model, but that vary in sub-model. Always take their descriptions with a grain of caution, and refer to the manufacturer's website for more accuracy.

The U4922-PK is a 1/4 turn 2-way diverter. It will give flow through the shower head or the hand shower. The U4929 is a toggle lever with 3 positions: showerhead or hand shower or both. I would highly recommend the U4929 model.
