## Questions & Answers

**Q: Who is responsible for product damage if delivered without a cushioning agent?**
A: Shipper

**Q: What if i am using small quantities of ro water? won’t using only ph down bring it down drastically? since there is no ph up, would it just stay stuck**
A: You can set the drip time on/off settings. The pump is the same used in hospital settings. While ph fluctuations is normal, this product will control it for you. Keep in mind that you can only set it up to add ph up or ph down, not both. My ph tends to naturally drift up, so I have the controller set to add ph down. The volume of the solution it can control is in the product description details.

**Q: What is the width of the ph probe?**
A: Hello there!
The width of the pH probe is 12 mm in diameter. Cheers!

**Q: Is this distributor legit?  This item sells for $400 minimum everywhere else. $575 in stores. I need this model.**
A: I had the same concerns as the rest of you. I bought it and totally happy that I did. If paying an extra 150 bucks or more for the same exact product is what gives you piece of mind. Then go spend the extra money. 

The mindset of you get what you pay for is not always correct. Not when comparing the exact same product at different prices. It’s not like the blue lab ph doser. It isn’t a competitor. It is literally the exact same product. Since most people that use this product is for pot.  If you sell the same batch and amount of pot to two different people at two different prices, do you get what you pay for? Or are both people buying the exact same thing, just at a different price.
