Quality and Price Guarantee!

We are a full service company offering a high quality converter at a low price.

 

 

Quality - We offer high quality products from SerialComm.  We do not search worldwide for the cheapest possible converter and pass the savings to the customer.  We strive to provide the best converter for the lowest price.  Many customers are interfacing to expensive equipment and are looking for quality without a large price tag. Satisfaction Guarantee - We offer a 100% 30 Day Satisfaction Guarantee which most companies do not offer.  If for any reason, you are not satisfied with the product just return it.  There will be no questions asked.  Many applications are complicated and it is possible that the product does not work as you anticipated, so why should you be stuck with the product.  We will return the full value of the order minus shipping costs. We do not add restocking fees when returning a product. Technical Support - We offer phone and email technical support.  If you need help selecting a product or are having problems getting your system working, technical support could be an invaluable service.  This is a quote from our competitor’s site: “Besides our tech info webpage, which provide lots of technical help and advice on installation and use of our products, we do not provide technical support.” Why would you want to buy a product with no phone or email technical support? Sales Support - We offer phone sales and customer support.  We accept credit card orders over the phone.  We will let you know whether products are in stock and reassure you that orders will ship same day if ordered with expedited shipping.  We offer many immediate customer support functions which are not available with email support.
 

Purchase Orders - We understand that large companies usually prefer to issue purchase orders rather than using credit cards.  We accept purchase orders with NET 30 terms in most cases.  We do not accept purchase orders from companies outside the US or Canada.  Not too many companies on the internet are willing to accept purchase orders but our company does.

 

  

Manufacturer's Warranty – SerialComm offers a 5-year manufacturer's workmanship warranty.  Within a 5 year period from the time of purchase, if a rare event of a malfunction should occur; SerialComm will replace your product.  Fill out our RMA form and we will issue you a RMA number for return of your product.   We do not issue refunds after 30 days of purchase.

  

Same Day Shipping - We can deliver your product to you by the next morning if necessary via FEDEX.  We almost always have all our products in stock and make a trip to FEDEX every day at 7:30 PM to send our express shipments.  Expedited FEDEX options are offered during the checkout process for you convenience.

 

Certifications - All of SerialComm's products are CE, FCC, ISO 9001, and IAF certified and most are RoHS certified.  These certifications are an investment in our products as well as an indication that we offer quality products.
