I rarely add reviews after ordering components because I think it wastes my time, but this time I think I need to give my comments since this purchase was too disappointing. Firstly, the seller forgot to ship one third of my components and they found it one week later after I made the payment. Secondly, the invoice they provided was wrong. Even after they sent the so called correct one, the total amount still has 10USD off. Thirdly, they shipped the DSP IC in the way as shown in the picture. And k don’t know if those DSP ICs are authentic or not although they insisted it was. This way of shipping the DSPs also make the IC pins a little bit tilted. Finay, some of the ICs they shipped are not working. Even as a Chinese and chated with the seller using Chinese, I find it was so hard to communicate with the seller. As a final advice, don’t go with them and you can save both your time and money.
