The Calibear dry top whip adapter is everything I need in a whip adapter. I can't ask for anything more. It is made well with good quality glass that doesn't feel cheap and/or too thin in your hand. It fits my Switch 2 perfectly and doesn't have unnecessary bulk like others that I've seen. The included tubing is the only negative as it is very bendable and bends to a pinch easily, cutting off the air flow. This is far from a deal breaker as many people already have tubing laying around already and if you don't it is very easy and cheap to get. The airflow is very good as it doesn't add any added restriction to the Switch 2. I love having the option and convenience of being able to use my Switch 2 with any of the glass in my collection. The best part about this adapter is the price/value. I've seen other brands that offer the same functionality and features with their adapters and the prices tend to be way too high.
It looks good but more importantly, it performs well, and the price is definitely reasonable. I highly recommend.
