I have a Colibri Trinidad and Colibri Oscar that both work very well . If you get a Colibri make sure you drain it totally before refilling and follow all the directions that come with it . I've had the Trinidad for about 3 years . I just got the Oscar about a month ago . I bought a Nibo Space , didn't last 6 months($20.00) , tried draining it , blowing it out with compressed air to no avail . I bought both my Colibri's on Ebay , payed a little more than half price , sellers name was "Hapashman" I believe . When getting anything on Ebay though always check the vendor's feedback .
