Q: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
A: 1
Rationale: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor
Q: My baby LOVES this teether!! I bought it for him when he was 3 months old (he started teething around 2.5 months) but it was hard for him to hold things since he was just starting to grab. This banana teether was very easy for him to grasp and put in his own mouth. The grip is great, it's very ergonomic for a baby and I love the feel of the silicone. Other teethers he would only use for a minute or so and get fussy or frustrated, but this teether can keep him occupied for awhile! Also sometimes if he's getting fussy while biting it, I'll take it and just gently brush his gums with the end and he loves it, sometimes he laughs haha. I've also gotten so many comments & compliments on how cute he looks chewing on his little banana. I now recommend this to all moms that have a teething baby to at least try.
