They have three colors available for each variant (Silver, Orange and Purple). For the Lightning Rabbit, it is retailing for US$20 (S$26) while the Old Skool Rabbit and Micro Rabbit cost US$15 (S$20) each. International Shipping is an additional US$6.75 (S$9).
There is only one length available for the cables which is 5 foot (1.5m).
I am not too sure whether they are using MFi certified lightning connectors because it was not mentioned on their website. However, I am not getting any “This cable or accessory is not certified and may not work reliably” error when I am using it to charge my iPhone 6 Plus.
