"A purchased product wasn't doing as expected so I mailed customer services initially to see if I received any response. A fast reply ensued and the respect given to me as a customer was second to none. Not only replacing the unit as expected they replaced the whole package without delay. Communications were a wonderful experience and I can wholeheartedly recommend Sainsmart as a superlative company to use.
The whole endeavour conducted at ZERO expense is amazing in today's market which backs up my proposition of using Sainsmart repeatedly where possible.
The goods themselves are excellent value for money and have additional features that their rivals fail to meet.
100% satisfaction."
