This product fell short in many aspects of jewelry making. Through trial and error, i found that the gemstone selector provided inaccurate results, making it unreliable for Arts and Crafts projects .The pros of this equipment are its size and portability, allowing for easy storage.

Overall, an underwhelming tool for jewelry making..See full review
