Waste of time, they do not ship fast or have good customer service

Website states orders are processed 1-24 hours, here we are a week later & there has been no updates or tracking information. I called & canceled my order & will no longer do business with HydroBuilder, spoke with two different people on different occasions & neither could give any information & did not offer any solution.

Find a More Reliable Souce

Hi, I purchased 125 20 gallon bags for our Loofah's here at our farm. As of this Friday, it will be 4 Weeks and they let me know it went back to the warehouse. 4 Weeks later.

Delivery is supposed to be next Monday, I have no faith in that. I recommend you find a more reliable source where you live. I am here in Michigan where this product was sent out. All the way to California, "by Mistake" Chelsea said.

Save your time and money and shop local.

Good Job

From locating the product through receipt of package, the whole process was well organized. Shipping cost was reasonable and delivered quickly. THANK YOU!

Didn't send the right product; $100 Restocking Fee on $160 order

NEVER shop here, they didn't send the right product, and are now insisting that we pay $100 restocking fee + $60 on shipping (meaning we don't get any money back).

I will never recommend or shop here again.

🗑RIP-OFF!

$38 for ice and a small little sachet. For the same price I could get 30 sachets directly from the source don't trust these guys! Go to TipTopbio.com the website listed on the sachet!
First time last time customer. These guys are definitely cut off!
