The Loomo LED mesh harness is good to its purpose, namely making my dogs visible at night. It certainly does that well. It was smaller and more lightly made than I expected, I'm not sure it would hold a determined dog...but it would be visible. I would have preferred slightly bigger (between L and XL, and stronger. I haven't achieved the 20 hour use out of a charge, I get less than 10, but I might be doing it wrong. One problem was that I was sent the incorrect charging leads. Overall 'good' and useful for visibility purposes.
