In my humble opinion as an aged hippie who has been chain smoking a pipe for over forty years, the Ylyycc 3 in 1 as sold by coolhighhappy is best of three purchased on Amazon. This is for initial quality, but I have high expectations for its continued excellence. The tamper is round and proper diameter for all pipes (even those have cake build up), and both the tamper and nozzle cleaner are adequately exposed to effect easy opening. Finally, but not least of all, the silhouette as a pipe is way cool.As for the also rans, the Executive Desktop Pipe Tool – Tamper, Reamer & Pick 3-in-1 Tool – Oak Wood & Stainless Steel – Heavy Duty tamper is too large, but a few minutes with the grinder in the garage will fix this. The Durable Matt Lightweight Stainless Steel Spike Tamper Reamer 3-in-1 Tobacco Pipe Tool is a puzzle in that the scraper sticks making withdrawal very difficult. This was not an initial condition, so I suspect something from my pocket has jammed the hinge.
