Showroom **RIP** - 6DOF project using 12v DC Motors, Sabertooth 2x60's (was MM's) and Arduinos + OSW

I wish I had just used Ebay as they are only £1 more expensive on there and at least your pretty much guaranteed to get your money back if there are any problems.

@SilentChill I purchased my motos on eBay. Seller is satisfyelectronics, 46428 positive, only 114 negative, member since 2010. They shipped to the states in just two weeks. So far two are working and two remain unopened. Not making any guarantees but at least it's eBay and PayPal, you will get your money back if faulty. I paid 45usd to get four units. That includes shipping.

Thanks @bruce stephen I think that's the way I will go as it's safer for refunds and problems.

Hey @Pit ... You may then remove your beloved statement that you like excessive destruction of H-Bridges ...

lol, some alternatives: "I do not like mass destructions, why we should use MMs?" or "I like MMs because I like to fail in my life" or "MMs will never die because they are D.O.A" or "Buy MMs from Aliexpress and begin to pray" or etc.

For a laugh this is my conversation with the guy who sold me the last 4 faulty MM's. All I want is my money back.

I'm sorry but I have had a lot of problems with other MM'S I have bought so I wanted to open a dispute straight away.
I'm sick and tired of poor quality moto monsters being sold on aliexpress.
I was hoping you would be different but it is not still faulty goods being sold.
I'm not being unpolite I just want a resolution very quickly.
I will get some videos to prove how poor the controllers are. I suggest you check the rest you have as they will probably all be faulty

Please refund ASAP
thanks,

yes I have all that information already how do you think I know how to wire and apply code to the Uno to run the MM.
Listen to me ........ your MM'S are faulty you need to check your stock they are very very poor chips.
I know how to use wire and test them you have the proof in the video !!!!
PLEASE REFUND AS YOUR GOODS ARE FAULTY.
PLEASE CHECK THE REST OF YOUR STOCK A LARGE NUMBER WILL BE FAULTY

OMGoodness...very stupid procedure. We all know it what a shit has been sold the last months. IMO they (re)sell only and they know not what they do.

给我回我的钱

"Give me my money back" in Chinese

@SilentChill - Did you use a Credit Card? You could always open a dispute with your card. If you buy goods and they are faulty and the seller does not respond the card issuer will take a look. Not sure if that extends "internationally", but worth a phone call to your card issuer at the very least / as a last resort. Use the words "Scam seller" etc...

Thanks @Archie but I used my debit card so I would struggle.

Think it's an expensive lesson learnt.

I will not use aliexpress at all, though it sounds all good for buyer protection and refunds returns it's appalling. Never again grrrrrrr

This is the end of the dispute I have escalated it couldn't be arsed waiting any longer. Best thing was the sent me a video of a guy these tin it as a dual half bridge and one side was fault LMFAO !!!! Unreal they have no idea what they are doing.

EVERYONE STAY CLEAR OF ALIEXPRESS. EVERYTHING GOOD IF NOTHING IS FAULTY OTHERWISE YOU HAVE FAULTS YOU HAVE LOST YOUR MONEY !!

Hello,
It is not polite to ignore messages and it's very bad business not to refund your customers when you have sold faulty goods.
Please refund my faulty goods.

Dear
all parts we test before shipping
and don't have any other customer complian this problem
so that is why we always check with you
and we ask you to make the video . but you only make one piece problem
engineer have told me. if one piece broken . he can understand . but if all 4pcs broken . he said is not possible . because all test before shipping.
and now he have find the problem of your way.
that is you connect wrong way .
you think A1 and A2 is together
but in fact . the right is A1 and B1 together .
pls check the video i sent to your email

I have 16 faulty monster moto that I have bought off aliexpress.
I am using it as 1 motor driver why don't you get your engineer to look at the schematic properly as he obviously does not know what he is talking about !!!
Stop trying to get out of the refund and just pay me the money back.
I have proved that each of the items has a different faults and you have no idea how to test the units obviously.
could you explain how you test them and what load you put on them to test or do you just use a multimeter ?
anyways that really doesn't matter just refund me.
you are selling faulty goods you need to test properly before selling them.
PLEASE JUST REFUND NOW IT'S GETTING BORING

Craig Hyde
2015-07-01 09:45:52
TRUST ME AND TEST ALL YOUR MONSTERMOTO'S THE WAY I HAVE OR ELSE YOU WILL GET MORE AND MORE DISPUTES.
Also in your video you are not using an external PSU for the MM I'm suprise you didn't burn your arduino out . very bad practice .
you need to put full voltage through the MM'S to test

Craig Hyde

You said this "and we ask you to make the video . but you only make one piece problem " no I tested all 4 you need to get someone who speaks English to translate Me speaking in the video.
I am getting sick of this you are not very good I will escalate to aliexpress tomorrow as you have not offered any type of solution. Your going round in circles. I know how to use these boards better than you and obviously your engineers.
Thanks for,well, doing nothing.

Oh I forgot this was his solution

What kind of firkin solution is that the dodgy retards. Guess I can say bye bye to my money.

Ya live ya learn ya move on,

Maybe sometime this summer I will get it all sorted pffffffff

This seller is a stupid f****** idiot. That said they know not what they do. I feel pity with you and I am very distinguished about all of that. The MMs would be a good choice , cheap and effective - and now it's all water under the bridge.

They are @Pit just got to get working ones lol even if they cost twice the price from a decent supplier that's not a problem. I will get some from eBay UK after I get my 15 new faulty ones from China lol. Even with all the loss it's still a lot cheaper than any other way.

lol, you stay still positively May the forces (MMs) be with you.

Fellows,
"Good quality is not cheap & cheap quality is not good"...............with all of your trouble, time wasted, money probably gone, you could have purchased the "good" higher priced ones and still been ahead of where you are now.......IMHO

Yes I know couldn't agree more @cthiggin but everyone wants a bargain. I have learnt my lesson here that's for sure thankfully not too much of an expensive one.

SilentChill,
Sure friend, everyone wants a bargain, "me" included...........but from years and years of experiences that I've had, most of my bargains have turned out as crap......again, IMHO....

Hope you get everything work out......

In general You may have right. Actually the MMs are very solid so there would be no reason to make them bad. If they are working the chips are very durable.
