Do not purchase anything from Lenovo. I ordered the $15 Lenovo computer speakers through my employer (HIED). They arrived and the main speaker sounds like there was something loose inside the speaker when sound is played through it. I contacted the company, which was incredibly difficult to find a contact number. They told me they would send a replacement right away. I have been in communication with them continuously over the past three months and they STILL have not sent the speakers. Today, when I gave them the order number provided to me from their official email, they could not find it. COME ON! It is a product being sold for $15! Why is it SOOOOO difficult to send a replacement? I have wasted so much time with this company. I will just get another product elsewhere. This is ridiculous.
