Very cheap indeed.
The difference is huge:

1) Input Wattage: Mine 880W, the one shown is 600W.

2) Throw distance: Mine 21mm, the one shown I believe is 8mm (it is not state in the web). (so mine is large throw machine like the Rupes Bigfoot LHR21, whereas the one you show is traditional DA).

3) ergonomics: Mine is try to mimic the rotary design (it is a Rupes + Flex combine), so it is longer in length. Your is shorter. No verdict here because ergonomics is personal preference.

4) Backing plate attachment menthod: Mine uses allen key with a spline feature on the backing plate head, so I do not need to use a wrench. Yours need to use a wrench to hold on the bearing nut otherwise it will never get tighten, wrench is usually come together with the package.

5) Backing plate choice: As mentioned above, I will be restricted to use the backing plate with the spline feature, so I basically can only use the two backing plates shown in my post only. I will have to buy from Maxshine for a replacement. Although I am curious also whether Rupes backing plate will fit on my machine. Yours is like universal, any common traditional DA backing plate choice can be used. So you will have less problem when come to re-stock.

Basically it is two different category of DA machine. Mine is large throw, the one shown by you is traditional DA.
I have one traditional DA myself too. Both have a place in my work, none replace the other.

The only thing I am concern with your machine is:

1) You do not have a chance to test it yourself. So you will never know the quality until it is shipped which by that time might be too late. Taobao electrical items always got risk, TianMao will be more reliable. Try search for same product from TianMao instead. Both Taobao and TianMao, like Aliexpress, all belong to Alibaba, same China man boss. Provided you have friend in China who can test for you upon receive the item, then the risk is lower because there is a policy of return given by Taobao. You can still do the return even when you are in Malaysia but the courier cost might not justify the action.

2) Because you didn't test it yourself or hear no other user feedback on forum before, you never know whether the motor will bog down under pressure or not. Forum member here who purchased China made rotary before experience this problem on certain cheap model. If it does bog down under pressure then it is pretty much useless. But again you will never know until you test it yourself or hear from previous user.

3) It is really cheap, too cheap to be good to trust but I cannot assert it is a bad product. The reason I say it is hard to believe because there is another identical machine carried by Aikka Malaysia:
Aikka DA Polisher
but it is selling at RM600+. Almost twice the price. Well we never know whether it is due to Aikka trying to make a huge profit margin or it is indeed two different grade of quality. I will suggest you email Aikka, find out which branch has a ready stock, go there and try it out yourself.

That is all I can feedback to you at the moment from the info you provide. I wish you find your machine soon.

Out of my league and out of my budget. 

Waiting reply from dodo juice Malaysia. Seems like buff daddy got good reviews. If it's cheaper than ultramate, can consider. Else fall back to random orbital.

Hi guys, wanna get your opinion. I live in an apartment where my parking is under a tree, so getting tree sap on my (white) car is like a daily thing to me.As I can't park somewhere else or chop off the tree, prevention is pretty much impossible.

What I do like to find out is, if there is any way that could make cleaning them off easier or faster. I wash my car weekly and I get really exhausted having to use a lot of elbow grease to 'push' away those tree sap. I was thinking about coating but I'm not sure if it would be really helpful.

Please share your thought, any tips or tricks would be much appreciated.

Polishing will prevent this?

Bro thanks for the input! Will go do some shopping this weekend! 

I noticed that my car recently developed a rough surface on the bottom half of each door panels. Its texture like fine sand, tried to apply a bit more pressure on them but they don't seem to come off.

What are those? They are not present on the other parts of my car, just exclusively on the bottom half of the door panels.

Anyone know the best way to protect and restore plastic bumper trim, i occidentally scratch my hrv back bumper. Using polisher to do it, now got patches white mark

Will the patches become more visible if blow hot air?

hmm.. any good recommendation on such products?  hopefully not too expensive one...
i'm looking at Meg's Headlight Protectant which cost RM 47..  anyone used that before? review?
