I can’t say I know drumming, but from what I can search up it’s apparently better than nothing. An electronic drum kit is better than a pad but not as good as a real kit. They all have different feels.
However, it seems that doing anything (even air drumming) is better than doing nothing.
If you are serious, then investigate lessons. You might be able to use real drums at your lessons and the pad for in-between. The teacher should be able to help you pick good exercises for using on the pad.
From what I’m searching up, it seems if you’re not doing lessons you’ll get bad habits regardless, but it shouldn’t prevent you from starting. Anything is better than doing nothing.
I have one of these that I use for Pi-hole. I bought it as soon as they were available. Didn’t realise it was 2012, seemed earlier than that.
