“I received these last week and two were defective. The company immediately responded and sent a coupon for 90% discount on another set.The bags are pretty thick and the slide is removeable; probably best for longer term storage of items to be frozen, although since they are silicone, they can be used in microwave”
“3 out of 6 were bad. Bought 12 total. They arrived in two packages of six. One package was fine the other 6 had 3 bad. Silicon solidified in the tube of the three.”
