Yes, it can be useful to order an extra LED flame as a backup. This way, you can continue to use your LED candle when the internal part needs to be replaced.
Good to know: frequently pressing on the flame with your hands to turn the candle on or off can cause wear and tear over time. The LED flame is a mechanical component and can be damaged or broken by frequent pressing.
We therefore advise you to let the timer function do most of the work and to operate the flame manually as little as possible. If you want to turn the candle on and off more often without touching the flame, it is best to choose LED candles that are compatible with a remote control.
