1--How do you choose which companies to work with?
 
2--Well, there are lots of things to consider. Quality and delivery times are as important as price. We also take into consideration technical support and after-sales service. We look for companies with a good track record. We place a few trial orders and if everything goes well, we put them on our approved list. It's important to choose companies you feel you can work closely with.
