I have been buying from AliExpress for around 5yrs and out of over 200items bought I've had 3 bad experiences. I recommend that when you are looking at items on this site that you check the ratings of each store and even if the ratings are quite good I would make a very small purchase initially to check out the quality, customer service and shipping speed time. When you purchase online with any store you are always taking a risk so I would keep the amount you spend always within your budget and thoroughly check the stores ratings
