I've never had any problems buying anything from Costco. Their prices are always great and their employees are always willing to help and are friendly.

Strengths: Very low cost. Friendly employees. Fast service.

Needs to improve: Not premium quality but you get what you pay for.

I've always thought Verizon was very reliable for both cell signal and customer service experience.

Strengths: Fast, reliable service. Cell phone signal is available almost everywhere. Customer service is friendly and prompt.

Needs to improve: Other service providers offer lower price deals and packages.
