This is an unreasonable BOI, 100%.
OP also fails to mention she AGREED to terms which clearly state there is no cash refund for animals purchased, and that she was in breach of those terms by filing a buyback through paypal, instead of taking store credit or replacement animals.
I don't understand the point of this BOI at all. You OP are in breach of terms, you are still waiting on PAYPAL'S decision on which side is in the right, since you refused to have your animals shipped, and then cited "Items not Received" as your paypal dispute reason... and there is no reason at all to sling mud about the growth rates of someone else's animals or declare them unhealthy, when there is no proof that this is a true statement at all.
I've been in the crested gecko hobby for nigh on 8 years. And I can state with certainty that 2-3yrs to reach adulthood is perfectly normal for a reptile, especially a crested gecko.
The OP seems quite focused on the fact that she powerfeeds insects to force her animals to adult size in under 2 years, and her reason for this BOI is being disappointed that she bought from a seller that does not partake in the practice.
I will be posting followups with photo evidence of the perfectly healthy animals in my collection and their perfectly healthy "slow" growth rates.
I have bought from the Harlequin Hoard in the past, and we co-own an adult female. I personally live mere blocks away from Margaret and have been in her gecko room numerous times. She has a thriving roach colony and feeds nothing but PFMC, the most celebrated diet in current seasons. She has healthy animals, and cares for them a great deal.
This BOI is unfounded and its obvious the OP agreed to all terms when they suited her, and then showed her untrustworthy nature as soon as she decided she'd overspent.
I will personally never sell to this person after seeing this ridiculous post. If I can't put trust in a buyer keeping their end of the bargain, what is the point? What is to stop people from pulling this same stunt AFTER they've received their animals? Personally this is now my opinion of the OP of this thread.
