After trying many, this one is the winner.
I support this brand.After testing, the following are the advantages of this particular brand vs the many similar others:1. The spout is slightly tapered for smoother, slower pour. The air hole is reasonably reachable for air control to slow down the pour a little but there can be improvements on the air intake design. But this one is OK. The air tube is extended long enough that your thumb can press and slow the air.2. The connection is all rubber instead of metal to rubber which is one of the most frequently first to break area. The all rubber all-in-one design is a lot less likely to break.3. The covering part is a lot better and better looking than most other brands. The lid or tube or whatever you call it. The part that covers the spout.. the dust cover. This brand is a lot better. Makes your bottles look fancier, less cheap.4. Wide bottleneck adapter is included. Many of the bottles such as tequila has a much wider bottleneck requiring adapter to fit properly. Tequila for the most part should be poured with a spout anyway. That extra glass slip on tequila bottle often cause drip. Therefore, a pouring device that comes with bottle adapter is essential. Probably mandatory in my opinon.5. The pour spout is more curved than other brands. Although the extra curvature is slight, that little bit extra curvature makes a world of difference when pouring a shot. You don't have to invert the bottle as vertical as you would with a more curved spout. A 45 to 60° poor angle is sufficient. Of course, if you intend is to have a lot of that bottle play bar flair, then if that's the case you would want to go with a straight spout. Otherwise a slightly curved is better suited.Now... The negatives the company can improve on:1. Include a small brush for cleaning? That'd be nice.2. Redesign the air intake tube to be even more effective. But already pretty good as mentioned.Hope this helps!I'm writing this from the perspective of home bar entertainment view point. What I would like to see is a product that is functional, effective, professional performance, but suited for home use. After having tried 6 or 7 brands, this one stood out.Thanks for reading!
