This is my 4th urn over the last 10-12 years. All supposedly SS (stainless steel). After 5 months of use, I am exceptionally pleased. My most recent urn (Professional Series) lasted only 19 months due to a NON-STAINLESS STEEL (SS) spigot retaining nut that “literally disintegrated!!!”Addendum: (from another review) the EXTERIOR wall indeed attracts a magnet, and hence IS NOT SS. However, the INTERIOR wall IS INDEED SS as a magnet WILL NOT stick to it.The PLUSES:1) it’s a true SS “double wall” – insulating and guards against burns (et al, INTERIOR wall is SS; EXTERIOR is not SS; but some polished/chrome steel)2) almost totally constructed of SS (spigot, exterior handles, and base excepted of course) – down to the internal spigot retainer nut. (This piece literally “disintegrated” on my former urn (the part wasn’t SS) – rendering the urn (Professional Series) useless as the spigot now leaked and any replacement spigot didn’t fit).3) advertised as a “100-cup” and CLEARLY DEFINES that cup as 5 oz, AND labels the alternate capacity as about 64 “8 oz cups”4) large-diameter base guards against “tip-over”5) environmentally-protected on/off switch6) brews relatively quick, but be warned! – the urn draws 1500W of power! (Other urns are typically 1000W -1200W)7) “warm” function definitely keeps the coffee hot8) easily able to fit tall cups & mugs under spigot (perhaps “too easy” as spigot sits a bit high on sidewall; et al)9) easy to clean10) “locking” cover minimizes spillage during transportThe MINUSES:1) difficult-to-read sight glass – and it’s not numerically labeled (no numbers, just “hash” marks)2) spigot is positioned a bit high on the urn sidewall; one must “tip” the urn forward to dispense the last cups of coffee.3) lack of a drip basket “cover” over the grounds basket (minor fault), which facilitates “even water distribution” over the grounds4) grounds basket doesn’t stay “centered” (level) on the uplift tube (aka “water pipe”). My countertop is level. But there is a noticeably wide gap between the basket rim and urn wall. Hence the basket/water pipe assembly invariably “leans over” and touches against the inside wall of the urn. Whether the urn cover “centers” the basket when locked down is difficult to ascertain. (A non-level basket would cause “uneven” distribution of liquid across the grounds).5) no automatic “shut-off” for safety; A minor fault – as attaching an on/off timer overcomes this issueFAULTS IN “OTHER” competitive URNS in the marketplace (that I’ve OWNED).-aluminum construction (aluminum tends to distort the taste of coffee)-utilizing ANY material of construction that is likely to corrode/disintegrate when in contact with coffee (coffee has a low ph of 4.0-5.0; “acidic”)-plastic (polymer) grounds basket (tends to “sag” over time).-a “tension spring” utilized under some grounds basket to lift/seal the basket under the cover, may fail-use of polymer “bands” to join segmented urns tend to break over time from heat fatigue-lack of a double-wall tends to over-brew (if grounds are not removed at the end of initial brewing cycle), and risks contact burns-total lack of a sight-glass-inadequate sight-glass “markings” – worse, no markings at all to determine coffee volume-small-diameter base-compared-to-height (a “tip-over” safety hazard)-not enough clearance (height) under spigot to accommodate most cups/mugs-a “cup” is a CUP!! – which is defined as 8 ounces!!! All marketing MUST CLEARLY INDICATE an ACCURATE capacity of the urn.Addendum 2 -update (8/14/23):-The urn continues to function exceptionally well; BEST urn I’ve ever had.-The heating element “well” does “build up” some debris that flakes/scrubs out very easily upon cleaning; (I’ve learned that this phenomenon is common in percolators).-As another owner reported, the polymer, top holder of the sight-glass fractured (probably due to heat-fatigue). It was an easy fix though as an appropriate-length stainless-steel screw re-attached this anchor easily.-I SOLVED THE “CENTERED” GROUNDS BASKET ISSUE! HOORAY! As I reported previously, I was very concerned about maintaining a LEVEL grounds basket to facilitate an EVEN DISTRIBUTION of water over the grounds. (Recall that I reported about the large “gap” between the edge of the basket and the inner wall causing the grounds basket to significantly lean to one side touching the inside urn wall).THE SOLUTION; 1) PURCHASE 3 APPROPRIATE-SIZED TEFLON WASHERS, 2) CUT A SLIT ON ONE SIDE, AND 3) SLIP EACH WASHER EQUIDISTANT ON THE BASKET EDGE, HENCE “FILLING IN” THE GAP!!!-I am now using a programmable 24-hour timer. After the urn has completed its initial brew cycle, I’ve set the timer to cycle “on & off” every 15-30 minutes to conserve energy. And to be sure that the urn is not inadvertently left “on” at the end-of-day. (Electricity is getting expensive!).The manufacturer now only needs to correct the aforesaid minor flaws and the urn will be rated “6 stars” in my analysis!
