Product review (5 stars): Perfect Solution for a Common Frustration
It's hard to imagine that anyone who is even the least bit handy is not familiar with Brasscraft water lines.  The quality is good and the price reasonable.  All-in-all, a fine interconnect.

This particular hose gets 5 stars from me because I think its very difficult for many folks to find short hoses with 3/8" compression fittings on both ends at their local stores.  As suggested by the product name, this hose is most often associated with dishwashers.  And, in general, one does not find a dishwasher within 16" of the water supply.  That's why the big box home stores usually have this in a 4' or 5' length.

But I believe this short version has a very specific application that can save many homeowners from frustration:  Plumbing up an RO feed line off the kitchen faucet feed.  Under-the-sink is typically a crowded place and can take a lot of abuse.  Its always a little concerning running poly tube every.  Brass or nickel valves and pre-fab braided hose is a preferable alternative.  But most 3-way valves (for an RO or DW split) are plumbed with male 3/8" compression fittings.  How are you gonna get from the angle valve of the water feed (usually 3/8" male out) to that 3/8" male-in on the 3-way?  Well, you could fab your own; or buy a brasscraft faucet or toilet line and find some series of adapters to convert the 'other' end to 3/8" compression; or maybe buy a 5' hose and curl up the extra under you sink; or, you could just buy this hose.

Yeah, I bought the hose.  I used to have 7 pieces to do the job that two of these hoses are doing now. The installation is much cleaner, so more reliable and easier to maintain.  Yeah, the hose costs about $5 more than it should, but that $5 is nothing compared to the pleasure of a well-done, straightforward, metal-valved, under-cabinet plumbing installation.
