Multiple other Cygnett chargers appear to be on sale.
Was looking up reviews for this charger and saw that it was on sale for $14.75 at COTD. Seems to retail around $45 - $50, a few places are even selling it for $60+.
Google reviews seem quite positive.
Be aware that with four devices plugged in it will likely not charge them all at 45W, that seems to be the max wattage for this charger. You should be able to get 45W with one USB-C device plugged in. More info here.
