Alibaba, A Chinese company, would have you believe that they will protect you in transactions from such thing as, wrong item sent or poor quality They use such terms as Trade Assurance. But not so.
We here in the West expect to get exactly what we order. But Chinese culture, sanctioned by Alibaba, seem to be that if you are sent something of what they consider equal or equivalent, that will suffice to complete the transaction. this is the case even if you can show a picture of what you have bought vs. the very different model you received. You can't return it economically because of the high cost to ship to China from the USA, costing us 10X more them for them with their government subsidized postal service.
So you contact Alibaba to help you resolve the dispute. However, you will loose unless there it is gross discrepancy. But if it is similar style, slightly different model of lesser quality or a color difference you will be out of luck. There are two problems here; they are Chinese company and the people doing the judging, are in some cases, not technical qualified. This is particularly true with the purchase of technical / industrial goods

While I am a small company owner and would advocate buying from small companies, say over Amazon. This is one of those small companies where the owner provides poor quality product and which is almost impossible return. Th suspender hardware was of poor quality and did not work. Had to get PayPal involved to get them to answer my request for return and to get my refund. My advice, buy elsewhere.

Just out of warranty, my z series CPAP produced and error code 99 and 66 which can not be reset and requiring a $140 service. Nice feature they built in to the product, pay them now and later. Consider hat in the price of this CPAP. Check the internet buzz on this problem.
Since it is a travel CPAP for me, I used it for about 30-40 nights on short trips over the warranty period, no physical damage. So this company is either dishonest or technically incompetent or maybe both? My Resporonics is 10 years old and works just fine.
The product is noisy comes with too short of a hose requiring you to sleep with the machine above your pillow.

Also known as HiThings.com They do not have the product they show in their catalog and will take your money and and not ship or communicate with you.In our case we wired them money and they did not ship nor could we contact them. Save your money and buy elsewhere.

This is basically a dishonest and a fraud company. They also go by the name of Shenzhen Instantware Information Technology Co. While they have a good website and catalogue they do not have the products indicated. We wired them money for product and they no longer communicate with us or have shipped any product. Since we are a professional purchasing company and have done many industrial transactions in China this company is dishonest. Contact us at *******@gmail.com for further details.

Their promise is to send you all your pills at one time in Packets. However, they do not do that. If they can't easily fill one of your prescriptions they will send the packets incomplete anyway.
Here's the dangerous part. When you receive your pills there will be no notification that pills are missing nothing noted in the box or on the packets. This may not be a problem if you only take a few pills.You might notice one missing. If you have to take many pills you may not notice one missing and start taking them without the required pill. They don't seem to think this is a problem since they say if you study your bill you can figure out that a pill or two is missing? In fact after I called them they still did not realize a pill was missing although it was confirmed on the original order.
When I signed up for the service I requested a co-pay estimate. It was 20 % more then what I was paying at CVS but I figured the convenience might be worth it. However when bill came it was 30% more for one month's supply. They do not do a 90 days' supply so you might have month end anxiety.
I will also say that the convenience is questionable.I received the packets in two white boxes taking up about a cubic foot of space. Instead of my 10 pills being in one packet they were in two. Previously my 30 day supply fit is a small compartmentalized plastic box the size of large book
All in all this service in not worth it and may be hazardous to your health.

Stay Away from Americare Respiratory Services. Slow service, bureaucratic overly excessive paper work, ill informed about medicare available supplies.
I need a new C-PAP machine under medicare and made the mistake of calling these people.
1. Took three weeks, an unnecessary trip to my doctor to fill out a form which I did not need because I was and existing user.
3. then could not tell me if I was eligible for a new machine saying the rules changed.
2 Then wanted me to sign a form, which was also unnecessary, saying I would pay $70/ month if not approved by Medicare.
4 Told me I was not eligible for the new Resprionics machine but would not tell me what machine they would supply.
This company is either dishonest, incompetent or just assumes we are all morons. That very day I told them to stuff it, I called a larger supplier. in ten minutes the latest Respironics machine was on order with just my medicare # and the my word that I would fax the prescription.

They claim to have world class service but not in returns. Absurdly slow return process. Slow return shipping. Slow to refund once received. They are certainly no Zappos. You either trust your customers or you don't.

Was majorly disappointing in the parts they sent, that did not match the manufactures part number. They also claim to have a no questions ask return policy, But try to get someone to respond with return instructions. Had to file a PayPal dispute. Suggest you pay a little more elsewhere.

Consistent great service and really free return policy. The others pretend to be Zappos but send wrong colors and sizes and hit you with a restocking fee, although they advertise free returns.

Anything to make a sale. Send the wrong color shoes just in case they stick. Then you want to return them? No problem except for the $6.95 restocking fee. In the fine print as part of the free return policy they advertise. These guy are very bad.

This is a sneaky company. There website makes you think you are doing business with a US based company buy they are in China. So anything you buy will come in one to two months.

You would like to think that Restoration Hardware (RH) is a class store, perhaps like Nordstrom were customers and quality come first, but nothing can be further from the truth. My experience deal with their outdoor furniture and customer service. The outdoor furniture is of poor quality and does not appear to be what it seems.
Unlike other outdoor furniture cushions that you might have had in the past, their cushions are not waterproof and will absorb water like sponges when wet. Plus when you buy them you sign an agreement that they can't be returned. RH solution is to buy plastic covers for each piece at $100 + per cover. In addition the fabric they use, while like being Sunbrella is not as durable and prone to mold. They claim that there cushions can't be waterproof and meet there standards of comfort. really? Plus they say they have that disclaimer in on the website which may be there but try to find it.
The furniture frames are also inferior, while the designs look terrific, you don't get what you see. The furniture appears to have a teak frame but may only have a teak foot accent. The frames are heavy painted iron and prone to rust in area near the sea. Surely for what they charge they could afford to give you great quality, like outdoor foam cushions and aluminum frames or real teak. If you don't mind rust stains on your patio or soggy moldy cushions then RH will not disappoint you.

I purchased a heavy outdoor umbrella base fro them. It came completely damaged because it was way under packed. Had to file an Amazon claim to get their attention. To satisfy that claim they sent an empty box hoping Amazon would close the case in their favor because they had sent a replacement. Did not work. But jeany files to know what a sleazy and dishonest company this really is.

Purchases a 100 pound umbrella base . It came damaged because it was poorly packaged. They said they would replace it because I filled a Amazon claim. To satisfy that claim they sent an empty box hoping that Amazon would close the case beciuase they could show they delivered a replacement! Sleazy and dishonest. Just want folks to know how thic company does business.

The worst customer service and return policy. Sent the wrong item and would not take it back. Had to file a Paypal claim.

Not buyer friendly. They know you can't return things to China becuase of the high shipping cost for us, but not for them. Very hard to prove poor quality or defective goods which AliExpress requires. So you are out of luck. The less than honest seller know that and will send you anything just to complete the transaction. And BTW takes for ever to get what ever they send.
