The CR series was the first of this type of waterheater. Navien learned from the problems and fixed them in the NR series. I originally had the CR240 and it gave me problem after the intial period. Navien eventually replaced it under warrenty with the NR-240 and it has worked like a charm for about two years now. BTW the picture in this ad shows the older model so beware. Check Navien's website for a picture of the newer model.

Several kids on my son's high school team have this bat. 5 have been returned to the manufacturer already for repairs. The plastic end caps break easily and my son's had a large dent. Don't waste your money on this junk.

The adaptor works perfect with the Chicco Keyfit 30 infant car seat. The seat clicks into place just as it does in the car base. No negatives on this item.
