Bests & Worsts Reviews from Amazon

I purchased a 5 pack of these 10 gallon grow bags one year ago and was very happy with the quality of the bags I received. The material was nice and durable with strong sturdy handles. I just received a shipment of 5 more 10 gallon bags and they are very poor quality. Flimsy thin fabric and weak handles. I reordered these bags because I liked the quality of the original ones I purchased. I would appreciate an explanation from the seller.
