Beck Arnley Type WS fluid

[ktom3001]

I noticed Rock Auto is carrying this for 1/2 the price of Toyota WS. Has anyone tried it? Are they the mfg for the Toyota fluid?
They also sell Aisin brand WS for ~$6 per quart. Just curious if either of these are better alternatives to Valvoline Maxlife. Not that there's anything wrong with Maxlife.

If it meets the Toyota WS specs, its good to go. I do not know whether Beck Arnley is the OEM for Toyota WS, my guess would be no and the OEM is probably some refinery in Japan or the region. Ive not tried Beck Arnley.

Here is a decent thread on alternatives to Toyota WS:
