    Great product and even better customer service.

    Package arrived damaged. Took a picture of box and broken item and it was resolved effortlessly with help from Annie on 2/21/2024. The colored 10x20 trays are one of my favorite garden purchases ever. Will be back for ten more for sure. 10 out of 10 products and service.

    When I received the dome it was cracked in two places. The dome is very flimsy

    Could be a little sturdier

    These domes are great as far as their overall design but I think it would be helpful for them to be a little sturdier so that they can take a tumble every now and then without breaking.

    Really nice quality

    The black domes were really smooth and just what I needed. I had been using the clear humidity domes and then covering with black fabric which wasn’t very efficient. It’s the perfect example of how the right tool for the job can streamline the process.
