Regardless building quality or actual user experience, this is wayyyy better than a 858D. I was excruciated by a 858D for over 2 years before getting a 957DW. It is way better.

I believe 957DW is exactly the same as a 957, just with added fancy temperature display. Control parameters and heater/blower are the same.
Blueskull, I think it would be very interesting to see some pictures of the insides of your 957DW. Quick USA replied to me today and said that the US version 957 and 957D use brushed motors, whereas the W versions use brushless motors.

Will do that later tonight or tomorrow.

Given it's market segment, it's actually better built than Aoyue and similarly constructed units (W.E.P., ...). So for $36, you got a heck of a bargain.  :-+ I prefer the pump inside the enclosure as there's no intake vents in the handle that can get clogged with dust or can be inadvertently covered up by the user, thus starving the unit for air (safety POV; less likely to start a fire).

Regarding the kinks in the hose, my 861DW's hose was kinked as well due to how it was packaged up at the factory. They've pretty much come out on their own as I lay it out in a large arc (no kinks from being wrapped in too tight a curve). I'll have to try the wrapping the hose in paper strips idea to see if I can't finish them off for good though.  >:D

Here is the tear down.

The 2 pictures are taken from left and right sides.

Then it comes the main board.

It is a single sided board, with a MCU, 3 TO220 and some misc parts.

Capacitors are Jamicon branded, not essentially a bad brand.

And the main transformer. Apparently the xfmr power sonly blower and controller, not heater.

I don't know how they managed to get 2 voltage rails from only 5 diodes. My guess is a bridge for blower and a half wave rectifier for controller.

The controller power supply is regulated from a 7805, and there is a TIP122 for blower control.

Seems like the TIP122 operates in linear mode, directly controlled by the knob, no PWM involved, hence the heatsink.

The heater HV side and controller side are isolated with an opto isolator. EMI is taken care by an X cap.

Nice pictures, thanks! I have been in contact with Quick USA customer service, and I'll follow up on this soon after my case is resolved.

My issue with the unit has been resolved. After contacting Quick USA customer service and requesting a replacement hose, they offered to replace my unit with a 957DW instead (rationale is that they believe it would be difficult / annoying for me to attempt to replace the hose myself). I paid for shipping my 957 to them, they paid for shipping the 957DW to me.

The 957DW I received is basically identical to blueskull's. Although the hose on this one is also a little kinky, it's much less severe than the unit I returned and does not interfere with positioning the hand piece. To my ears, the brushless motor sounds slightly less noisy and noticeably less "buzzy" than the brushed one. Curiously, claimed power consumption for the 957 W models is 400W vs 580W for the 957 non-W models.

I highly recommend the 957DW, although it confuses me why there exists a W and non-W version in the first place. Quick USA customer service is also responsive and easy to deal with.

Hi,

I purchased the 957DW rework station based on the good comments on this forum. The station works well but there is an annoying scratching noise when the fan is running. The company is willing to replace the unit but since I am in Canada, the shipping costs are high.

Can anyone with this station tell me if this sound is "normal" (audio file in attachment) ?

Thanks a lot

Sounds to me like the squirrel blades are striking the fan housing intermittently, so No, I wouldn't call that normal.

It may be fixable however, which would save you the shipping cost.  :-+

Well, the scratchy noise was not normal. I sent the unit back to Quik and the replacement one works well. It's a good unit for the price but I think there is a lack in quality control.

Quick 861DW it is not
looks like any other 858, the sad part is its a legit Quick product http://www.quick-usa.com/index.php?route=product/product&path=60&product_id=93
just looked at their other products and its 90% typical auoye crap, I only knew them from 861(very good hotair)

I DISAGREE. The unit shown in the pictures does not look like genuine Quick to me. It appears to be a knock-off low-quality unit from one of the many equipment counterfeiters in China. I look for the TEAL BAND on the handle of the hot air gun and the back of the machines to tell if they are genuine. In the case of this machine, the air hose is a perfect example of what to look for in non-genuine. Compare it closely with the machines found at http://www.quick-global.com/ which is the genuine Quick product ONLY.

It is a genuine quick, although cheap model. It's good but not as good as 861. Jamicon capacitors is one of proofs as Quick uses them extensively. 858 stations have nothing common with quick 957 as they use blower in the handle.

Hi guys,

I bought Quick 957DW+ hot air rework station based on your reccommendation and it was delivered to my doors couple days ago right from China. I was surprised by the compact size of the whole station - I thought these are much much bigger :) Anyway, everything is working properly as it should. Also the inside of the station is quite well organized (there are Jamicon capacitors inside). The rubber tube was bent a little bit as usually but I left it couple days in normal working position and it looks OK right now. Overall, I am quite satisfied :)
