Boeshield T9 is WD40 of the future, I’ve been using it on stuff for about 2 years, and it is a million times better. I use it on electric motors, bike chains, gate locks.  It lasts a lot longer than WD, lubricates, and protects better!! http://boeshield.com/ t9-products

The Altec Lansing iMW575 Life Jacket Bluetooth Speaker.  Previously I had a JBL Charge.  The Altec speaker is 10X better than the JBL Charge, longer battery life, cleaner sound with deeper base, and it’s water proof!!  I take it tubing and kayaking and it works perfect!  It has a USB charging port to charge your devices, and a micro USB to charge the unit.  http://www.amazon.com/gp/product/B00JYQOXAO?altec_lansing
