I just resently ordered my RO/DI unit.
I was looking at the one you posted but then I looked at the warranty
Warranty Information and Return Policy
14 days DOA (Dead On Arrival) warranty:
I found one that had a 2 year warranty but I went w/ a Typhoon

It has the clear canisters and a Lifetime warranty.
May be a bit more but i rather pay a bit more now and not have to worry vs paying less and wishing I hadnt.
by the time I get home today I should have my RO/DI unit waiting for me hehe
