I’ve used it on one holiday, it was pretty handy, but I could also cold water sterilise as I did with bottles anyway. I wouldn’t buy it new. If you bring 2-3 dummies along, you should have enough sterile ones for the day.
I have it ! It works as it’s handy to do it so when I am out and about
We have the mini uv steriliser & the bigger Nuby one. We keep the mini in our change bag & use it for dummies or small teethers when out. I wipe them with a boots baby anti bac wipe first, then pop in steriliser if she chucks them on the floor.
I havent used the nubi uv, but I have used the tommee tippee uv steriliser for thr last year and loved it. Would deffo go uv again if I had another. I assume they would be similar both being uv.
