First, the good: easy to use, easy to clean, very gentle and does as good a job or better than a traditional bulb aspirator, clear design means you can see what you're getting (I guess this could also be a drawback for the squeamish!).
What I don't like: the biggest disappointment was that it didn't do a much better job than the bulb. I wanted it to blow the bulb out of the water, but really, it doesn't. You still need saline drops to loosen any crusty stuff. I do get less fussing from my toddler, but I think this is mainly because he finds the Nosefrida so fascinating. He figured out how to do it himself the first time we used it (not that I recommend that!). [There's a Youtube video waiting to happen, Heather. — Ed.] Of course, this also means that he gets super-grabby and there's a lot of this thing to grab so sometimes getting it in his nostril in the first place is a struggle. Also, maybe it's just me, but trying to hold a wiggly toddler, keep him from pulling on the tube AND keeping the mouthpiece in my mouth makes me drool; not so fun.
Another downside is that Nosefrida recommends that you replace the filter after every use, and it only comes with, I think, 4 or 5 filters. After that, you'd need to order replacement filter sets (sold in sets of 20 for $2.50). Now truthfully, I'm not replacing the filter every time. Normal daily use doesn't seem to contaminate the filter at all, so I'm leaving it in for several uses. Maybe that's gross, I don't know, but it seems clean to me. You can see how far the goop travels up the tube and it never gets anywhere near the filter. (I do wash the tube after every use.) But worried types who want to follow the instructions to the letter will find this gets pricey fast.
I guess I would recommend it overall, but I think it would be best for a small baby who's not so grabby; might make a nice shower gift along with a couple replacement filter packs and a bottle of saline drops.
Thanks for letting us try it out!
