Review on Genuine 15277756 Rear Window Wiper Arm: High-Quality Replacement for Chevrolet Tahoe, Cadillac Escalade, GMC Yukon (2007-2014) - OEM Blade: 12 by James Mangum

EVERYTHING is perfect except for one thing. No installation tool is supplied. Your normal normal tools that everyone has will work. However, there is a useful tool ($12) that is worth the extra money. It's not necessary, but it makes things easier, and for a non-mechanic like me, it's eliminated the "I won't break anything else on my machine" worry I always get when trying to DIY a project to perform. The product looks the same as the original. The tool made me feel like a top notch mechanic.
