This is pretty consistent with what I stated in the other thread. DDC's are by far the most popular and most sold pumps. With such a large volume, they're bound to have failures in proportion to the volume sold. You also have to consider that XS members tend to gravitate toward the best performing pump. Couple those two things together and you'll see a possible explanation for why we see more complaints about DDC failures.

Ex: 100,000 DDC's are sold with a 1% reported failure rate = 1000 failures
10,000 D5's are sold with a 1% reported failure rate = 100 failures

Say that about 1/10 of failed pumps belong to a vocal owner (after many years as a congressional intern, we're taught that every angry letter from a constituent means 10 other people feel the same way but are too lazy to write).

1000 failed DDC's x 10% = 100 posts on XS about a horrible DDC death
100 failed D5's x 10% = 10 posts on XS that are drowned out by very vocal DDC owners.

In conclusion, with Gabe's reporting, the DDC failure rate might be the same as the D5's. However, due to the popularity of the pump and the nature of the this forum, we just tend to believe it fails a lot more than it does.

the DDCs are NOT that much more popular than the D5s, not ten times at all. my guess is they are very close to even. there are many WCers out there not on this forum that see the high GPH of the D5 and grab it over the DDC.
