My Swesara G4 bulbs were revived in 3 days, good fast delivery. G4 bulbs are popular in home appliances. I don't think it's a complex product that I need a well-known brand for, just a consumable. Based on my research, Swesara G4 bulbs are the most economical ($3.99), competitor G4 bulbs are much more expensive ($7-15) that I found at Revain. The bulb is bright and meets my needs. Highly recommended for regular home use.
