Almost a month and I’m still waiting for my 3 zappers
I’m still waiting for my 3 zappers, I been sending messages and they told me first that they were back order then they received them and told me they sent them a week ago they give me a tracking number that said only the label was created when I post my order that was 3 weeks ago and they told me the USPS office sometimes doesn’t update the tracking information, I don’t know what to think is really a long waiting time, you need to fix that

Went above and beyond
I made an order with singular and the experience was great. They are easy to communicate with and willing to work with you any way they can. These guys went above and beyond and went out of their way when I ordered a pack of 10 and didn't realize it needed two weeks before it shipped. They shipped it in a week for me and rushed it because I was leaving out of the country.
