Here’s what consumers have asked with answers from Walmart staff and previous consumers.
The reviews are 4.6 out of 5. They are LED and don't easily break.
No, I've read enough negative reviews of Shipping Pass to be convinced it's a waste of money. I think if you order frequently, they begin using Fedex Smart Post rather than Fedex Ground. Although this doesn't make sense, Walmart doesn't seem to appreciate those of us who place regular online orders for home delivery. I've been placing two online orders a month for essentials like cat food while recuperating from surgery (closest Walmart is a 200 mile drive). Service on each order is deteriorating and watch out for cancelled orders they don't notify you about--you'll have to contact them to get them to refund your money on a cancelled order. Until they improve their distribution, customer service and computer systems, Walmart will never be a threat to Amazon.
