The materials that are used to construct bowls and pipes, such as thick borosilicate glass or wood is important both to the performance of the product and the overall durability. The type of material used, how that material can affect the performance, and the overall quality of that type of material when comparing them to other competing products operating in the same market.
It is essential to consider different bowl and pipe styles, the design, the construction, the components and the ease of use by the end user. Bowls and pipes have multiple designs and are constructed differently, so it is important to consider the design preference and the smoking experience desired.
Performance refers to how well bowls or pipes function compared to the buyer's expectation. A buyer's expectation is generally shaped by both their history with using similar products and any guarantees of performance or expectations being set by the product manufacturer. Guarantees and promises are taken into consideration when measuring performance.
Based on the materials that are used to construct bowls and pipes, they need to be durable for long term use. Durability is the ability of a product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime.
While value is something that can be difficult to measure, it is something that can be compared between similar products. During consideration of different bowls and pipes, the value the average buyer will see compared to how much they have financially invested into the product is reviewed.
