On Tuesday, Hannah LaCaze found a small package from Instacart in her mailbox. The grocery delivery company had pledged to outfit more than 100,000 of its shoppers with “health and safety kits,” each containing a reusable face mask, a forehead thermometer, and hand sanitizer. LaCaze, a shopper in Texas, requested one right away, and after a few weeks it had finally arrived. But when she opened the plastic envelope, something seemed wrong. “It had a smell,” she says. “Then I noticed it was wet.” Inside, the bottle of hand sanitizer had burst, soaking everything else. The thermometer, a small strip of temperature-reactive paper, had ripped in half. When she wrung out the face mask, black dye dripped into the sink.

LaCaze posted a video of her tragic unboxing to a closed Facebook group for Instacart shoppers around the country. Quickly, in the comments, workers began to commiserate. “Mine was soaked also,” one person wrote. “I pulled it out of the mailbox and it was dripping everywhere,” wrote another. WIRED reviewed the thread, along with several additional posts on Instacart Facebook groups where more shoppers claimed that their kits arrived damaged. Other shoppers, on social media and in interviews with WIRED, say they too were disappointed with the supplies they received. A spokesperson for Instacart declined to comment on how the kits are manufactured or on the quality of the items inside.

It isn’t the first time Instacart shoppers have lambasted the company’s response to the coronavirus pandemic. As Covid-19 cases mounted across the US in March, a group of workers staged a nationwide strike, demanding Instacart provide disinfecting supplies, hazard pay, and expanded sick leave policies. On April 2, Instacart announced that it would provide the health and safety kits, but over a dozen shoppers told WIRED that they had trouble even ordering the kits, which were frequently listed as “out of stock” online.

More Instacart shoppers have come forward with complaints about the kits since the company began shipping them last week. “The mask is a joke,” says Amy V., an Instacart worker who received her safety kit this week. (She asked to withhold her last name, so as to not jeopardize her main source of income.) The Centers for Disease Control and Prevention, which has encouraged Americans to wear cloth face coverings in public to help prevent the spread of Covid-19, recommends that cloth masks include multiple layers of fabric and fit snugly; workers describe the ones in their Instacart safety kits as single-ply, thin, and stretchy. “If you hold it up to a window, you can see right through it,” says Amy. “Someone could use it in a wet T-shirt contest.” Instead of elastic, two slits have been cut into the sides as ear holes. Another shopper told WIRED that the mask is so thin that it was “effortless to blow out a lighter with it on,” and that she worried it didn’t meet CDC guidelines.

Some workers who spoke to WIRED also expressed skepticism about the forehead thermometers they received in their kits. The paper thermometers change color based on temperature and are meant to indicate when a person has a fever, one of the symptoms of Covid-19. As of Thursday, Instacart no longer listed the thermometer as part of its health and safety kit. A spokesperson for the company said that thousands of shoppers were still receiving thermometers, but that the contents of each kit might vary as Instacart works to procure enough supplies for every shopper on the platform.

Shortages of supplies like hand sanitizer and masks have been a constant since the early days of the public health crisis. Instacart has said it is working with a third-party manufacturer to make its hand sanitizers, and will only provide two six-ounce bottles to each shopper.
