    Soil Acidifier

    All went very well. Product is what it is supposed to be; 90% sulfur. Very satisfied. Just TILLED it into garden prior to planting tomatoes, so it will be a while to find out positive effects.

    Good product

    Good price even with shipping charges. Looks like quality product. If I can make a suggestion, before putting the bag in a box, put some shipping tape over the mouth of the bag where you would pour it out. There was probably a cup of product that had escaped the bag from the pour spout during transit.

    Delivered in Good Condition and On Time

    I could not find this product locally due to time of year so I had to order from the South. With shipping, it actually cost the same as buying from the local stores I know about. product is consistent in size and easy to use. The bags are strong and there was no damage in shipping. I have used some in the fall weather and will have to wait to see how it works.

    Sulfur for high Ph

    Don't know what to expect from the product. I'm following directions from a consultant who did my soil test.. I'll know more in my next soil test.

    Shipped securely

    I received my 50lbs bags packed in boxes for protection, nice. I've just spread the pellets so i can't comment on the effect of the product maybe in a couple of months I will see results

    Quick Delivery

    Product was packaged well and delivered much quicker then I thought it would be. Pellets are solid pieces. Seems other places have stopped selling the 50lbs bags so even with shipping charges added it still worked out cheaper then 3 X 15lb bags.

    Package arrived quickly and in excellent shape. Will know if application has worked when I check the ph level in spring.
