Professional Assessment of my sons Product Design

Information for the business: Urgent immediate response needed
Design details: My son has just designed a product for his college A Level Design and Technology project and urgently needs an assessment of his design.

I need an experienced professional product designer who would be kind enough for a minimum fee to evaluate the design
in say 50 words giving their feedback on the design and what is good about it and how it could be improved.

I have included the file and will send small amount of money to the most useful review. Thanking you kindly.
Target audience: Professional Product Designers
Ideas for the visual style: N/A
Extra notes: This is not a complicated task. If you are a product designer it should be a very quick thing. Your judgement are very valuable for a student designer especially if they are positive and constructive.
