Obviously they still have overwhelming support, but that's 3 guys now who arent crazy about their Dev filter.
What's not to love? I'm just about to buy one this spring.
Aesthetically, mine looks like a tin can, more or less, and can appear beat up looking fairly easily; they roll over sometimes, which looks sloppy, and causes the "beat-up" look I described.
Functionally, the lock levers need adjusting too often; the filter bag holder does not fit neatly in the filter casing; and a consequence of the latter, is that the top does not fit properly and sucks air around the edge.
On the positive side:
The filter casing is large and permits lots of air to flow through it; the large casing allows for a large bag to catch large amounts of debris; the stainless steel casing is tough and well made strength wise; the filter bag holder is well designed for maximum flow and made from good material; the removable top is interchangeable for replacement.
