Chasrock Services is proud to be:

( ISTA 6-FEDEX_A Protocol Certified )

This is a registered certification in electronic packaging.

We are approved to safely ship any electronics up to and including 150 lb. packages.

The ISTA 6-FEDEX A Protocol is an earned certification.

This is achieved by packaging and shipping electronics to the FedEx packaging laboratory, in Collierville, Tennessee

They put that package through rigorous testing including the following:

Shock Test: (10 random drops from 30 Inches)

Compression Test: The package is then tested in a press at 976.94 lbs. of pressure.

Vibration Test: The package is then put on a vibration table and violently shaken for 45 minutes.

You must pass all three tests without any damage, cosmetically or functionality.

 

These will be double boxed, surrounded in foam to insure safe undamaged delivery to your home or business. Yes, the shipping cost is a little high, but electronics are fragile and do require a lot of packaging and time to get them done right. I think it's worth a few extra bucks, because they can't be replaced. A note for you eBay global customers: ( I will get it to your door safely and insured.)

P.S. My posted shipping price is always the total!

I pride myself on extreme over protective packaging. (Please see my feedback!) I will only ship to the 48 contiguous states and I encourage eBay global shipping. Payment is expected in 48 hours of purchase and on the same token they will ship on the next business day. If you need more time, just send a message and we will work something out.
