Checks out. — Legitimate

"Most researched probiotic for infant colic"
DSM 17938 has 50+ published clinical trials. A 2018 systematic review in Nutrients confirmed reduced crying in breastfed colicky infants.

"Clinically shown to reduce crying time"
A 2014 Cochrane-style meta-analysis found L. reuteri DSM 17938 cut crying by ~50 min/day in breastfed infants — not formula-fed.
PubMed: Sung et al. 2014, BMJ -
"Works for all infants with colic"
Page doesn't distinguish: RCT evidence is strong for breastfed infants, weak or null for formula-fed babies.

"Price vs. alternatives"
At $0.83/day, BioGaia costs the same as Gerber Soothe Drops (~$25), which uses the same strain. No premium penalty here.
Consumer advice
If your baby has colic and is breastfed, this is one of the few infant supplements with genuine clinical trial support — it's a reasonable thing to try. Formula-fed infants show weaker benefit in the research, so manage expectations there. The 5 mL bottle lasts about a month at 5 drops/day, making the $25 price fair. You can find it at Target or Walmart for the same price, so no need to pay shipping. Don't expect miracles — colic typically resolves by 3-4 months on its own, and this may just shorten the misery window.
