We sold many gm tech2 to all over the world, but many customers are confused about which one to choose. sp23 or sp23-1
These are the difference between them
both items have the same functions, just packing is different
SP23 Case pack and free shipping 329usd
sp23-1 is a carton pack and without shipping 220usd.
that is the only difference if you like carton one to save money, choose sp23-1
if you like to save the parts in the case, so choose sp23.
