I got a pack from Peng and I thought I would provide you with my experience. To start, I want to add that I don't know Peng at all and my relationship with him is buyer-seller and I learned of him from his sale threads.
1. Communication was Peng was timely and he answered my questions promptly. I always knew the status of things and was never confused or unsure.
2. I asked and he agreed to hold the frags for two weeks so they can heal. My experiences with fresh cut frags were not good so I appreciated this.
3. Alk was 7.7 using Salifert and water temp was 75 degrees when it arrived
3. The box that the frags arrived was very professional.
4. The frags were doubled bag and well packaged. For reference the coin is a quarter. See below:
5. Frags sizes were good to very good. The frags I really wanted were the HOTO and Icefire. Peng gave me a great deals on the rest so I couldn't resist.
6. I appreciate the size of the HOTO. It was more than expected. The pics were taken under ambient room lighting with an iPhone 6. The color can easily be seen even now. It does seem a little more purple than blue but I think that is due to lighting. My lights in my tank are off so I can't tell what they will be under Radiums.
My experiences with Peng was great and I would recommend him based on my experiences. Hope this helps those who are on the fence.
