Incorporate Testimonials Effectively

I want to incorporate customer testimonials into my sales copy for [Product/Service]. Here are a few examples:
- Testimonial 1: "[Quote from customer 1]"
- Testimonial 2: "[Quote from customer 2]"
- Testimonial 3: "[Quote from customer 3]"

Suggest 3-4 strategic ways to weave these testimonials (or key phrases from them) into the sales copy. Consider placing them near sections that discuss [Mention key benefits, e.g., 'ease of use'] or address [Mention potential objections, e.g., 'concerns about complexity']. Explain the rationale for each placement.
