Is $2,000 to install two 47-foot gutters with two 90-degree angles a fair price?

I am about to pay $2000 for this gutter job. The installers were done within 2 hours. After our first rain, I noticed water dripping from the bottom of the angled pieces, so I grabbed my ladder to check it out and found a leak. I also tested the gutter myself by pouring water into it, and it indeed leaks underneath the angled sections. I am wondering if I am too picky or if I should tell them to come back and fix it. It actually looks great from the ground, and the only reason I went up there is because I noticed the drip, but wasn’t very impressed with what I found.
