The materials that are used to construct bongs, such as thick borosilicate glass or silicone are important both to the performance 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 is reviewed when comparing to other competing products operating in the same market.
It is essential to consider different bong styles, the design, the construction, the components and the ease of use by the end user. Bongs have multiple designs and are constructed differently, so it is important to review the styles and the smoking experience desired. Also, the overall construction should be consistent among multiples of the same product being sold to consumers.
Performance refers to how well a bong functions compared to the buyer's expectation. A buyer's expectation is generally shaped by both their history with using similar bongs or water pipes 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 bongs, they need to be durable for long term use and be able to withstand heat. 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 bongs, the value the average buyer will see compared to how much they have financially invested into the product is reviewed.
