I have been using the thin and skinny pre press mold for about a month, with great results. So nice that it is made to fit the rosin bag perfectly, helps get all the rosin out easily. Great price compared to the competitors, great customer service, nothing but positive reviews here.
For me, exactly 4 grams is perfect for this press, nice to be able to make consistent batches of rosin. (Posted on 5/29/2018)
