You can expect a lot of problems with resistive contacts.

Sandisk has stop it on their sansa... it was always a critical issue within few months.

 

The only cheap (non optical) good design was that :

 

The X3 odd layout is a big mistake.

Optical wheel was the solution...

All cheap mice uses them.

 

...Still searching for a good DAP...

...and feel alone forever

I think the quality of a part has a lot to do with it's longevity and functionality. I have a Sansa View with resistive wheel from 2007 that still works perfectly.

There is always someone... who have no problem at all :bigsmile_face:... some of them have seen the martians

 

So why implement optical coders absolutely everywhere instead of cheaper resitive contacts (rotative commutators)...

Why use brushless motors... instead of half cost brushed...

Because rotative resistive commutators are not reliable at all.

I like that you think Clips are reliable. Horses for course. Brushed motors can be better for many uses. Opto may be better but it may also be unnecessary for the same reliability. Optical doesn't have perfect reliability either. Talk to anyone that uses optocouplers. Their reliability is no better than a sealed metal relay. In fact their maximum useful life may be less.

Google is our friend...

 

hells on wheels :

I didn't know FiiO was buying their wheels from Sansa. Nice self portrait. Thank god for auto focus.  

 

Google is your friend. Do the same search for the View. Wheel problems are in the noise with any other issue. It's not just me, it's you thinking every wheel is the same.

Now you know how i'm beautiful  :biggrin:

 

It was a big issue... a past experience in a R&D departement...  they have tried all commutators avaliable in the market and after month of tests the only reliable one was a mercury commutator.

The office trash can was full of defective friction commutators (all of them was the best quality avaliable WW)

 

Hifiman too...

 

A commutator contact endures a lot of friction (insignificant on a simple button) and they are not reliable at all...

I guess I'll have to keep my fingers crossed. I still prefer the wheel to other options and if this is the only way to get it, I'm happy to takes my chances seeing how well a less cheap product has held up for me.:ksc75smile: See the earlier posts about patent rights.

You are right...

But it's bad design... an optical wheel or normal key layout should be better IMHO

 

The image of FIIO would be very compromised if their expensive players suffer from a lot of defective scoll wheels like the sansa fuze.

 

Let's see it... in some months :popcorn: 

 

And after...

See X5 now released an exciting, at least in China. I know FiiO a niche market, the audio. However, I want them to try to do a real flagship DAP. I want to have an alternative to the AK offerings, calyx

X7 check prior posts wink.gif

I'll put pix later but for now I can say the UI of the X5 to be quite fast. That was a pleasant/welcoming surprise.

But I think I need a quick instructional lesson on the button functions though. It took me awhile to work out the Main Menu, back, forward, etc.

So you have it, wow. Looking forward to read your impressions.
