Dynamo is most known for producing coin operated pool tables. The older Dynamo coin ops are tanks. As a table they play much better than most coin tables on the market with a standard set of balls. If you are using it as a coin table, play does seem compromised due to the heavier cue ball used to trip the cue ball return but that goes away when the table comes home and a standard set of balls gets put on it.
Dynamo did make a line of home tables for a time. They are low end and poor quality but the ones we have encountered went together really well and play decent after. They aren’t a bad table on really short money. For a time Dynamo (Valley-Dynamo) was owned by Brunswick however currently Valley-Dynamo is owned by a group which also owns Sun Glow, Champion Shuffleboard, Connelly Billiards and Tornado Foosball. Buying new, the coin tables are a good purchase. Used Dynamo home tables are only worth about $100 max pre install and are not the quality of other $100 value tables on the market, but if they present themselves to you for the right $ and none of the other tables are readily available then go for it. Dynamo coin tables should sell used starting around $300–$500 for an older model and $800 to $1000 for a newer one.
