I would say smarz sdn bhd is an scam because of the following reasons:
1. if they had iphone 4 factory unlocked 32gb for $680 they would have sold more than 5000 units phoes in less than 24 hours...
2. I know more than 15 of top supplier of hk ,dubai and Singapore and none of them have heard of them.
2. The only referral they have provided to me has stated their company is 99% has fake phones or does not exist. ( i can send you the screenshot of our conversion with thier USA referral...)
3. the domain name of the website
http://www.smarzwarehouse.com/ is under a "nigerian" first and last name : SULAIMAN ADEAGBO
4. They do not have one credible verified account in any of the b2b business or well-known websites.( gsmexchange, alibaba...
5. they do not offer "fly and buy" the guy says you have to pay 30% advance , then you can come and pick up the phones!!
6. they provided pictures as proof of stock for iphone 4. ( chines iphone clones boxes looks exactly like the real one so there is no way that you can say the pictures can proof anything...).
7. they offer paypal for the payment for cash advance but let me tell you this , you can open a business paypal account ,verified with VCC and bank for $10 ( what they do is they get the payment and withdraw the money to bank account and close the account and put some tracking number to shut paypal's mouth and paypal is not responsible for anything as lon as there is a tracking number to your verified address...) .
8. they do not offer any kind of escrow payment for the 30% ,even tho i said i will pay the 30% with escrow and pay you the whole money in cash after i pick up the phones and we can cancel the escrow payment after that.
So finally , if it sound too good to be true IT IS TOO GOOD TO BE TRUE.but i shoud say they are very professional.
