I own two, straight, classic stems. A Meer Genoa and a Meer Plymouth bowl.
Chambers on these bowls are a bit smaller in diameter, but there are bowls available that are more normal sized.
Issue I had with one of the stems was that the end of the casting had flash on it blocking the airway. I contacted Falcon, and they emailed me back asking for the model, and saying they would probably replace it... then I never heard from them again. Emailed them asking what's up, no response. Been a couple months, so customer service is kinda nebulous. I just drilled out the end and got rid of the flash blocking the airway.
They are good smokers. Draw is open. You can make your own filters by wrapping a pipe cleaner around the barrel of a pen, and cutting it with a pair of diagonal cutters. I fill the straight section at the bottom of the bowl with granulated active charcoal (A homemade charcoal filter), it takes the bite out of the Virginias.
Seems people either love them or hate them... Quicker cleanup than a Kirsten. But I love my Kirstens too.
For the relatively inexpensive price, I'd say go for it.
