Yeah,fitted one a week ago.
Perfect for me, all I wanted was the remote open/closing of the roof.
The one touch opening/closing with the the console switch is a bonus as is operating while moving.
Ordered the r170 my mistake but they swapped it for an extra £20 for the r171 model,only problem I had was on the right hand drive r171's couldn't find a live red wire in the harness so had to do a lot of searching to find a tap off the light switch.
Works fine and I saved a bit of money over other models?

Andy, if you order your SmartTop from the USA, just be aware that you might get charged import duties, tax and fees when it arrives in the UK. I ordered mine from PPCGB and, with 5% discount for liking their Facebook page, I think it cost me around £230 (with next day delivery, and no worries about additional costs/fees).
If you're interested in buying from PPCGB (I have no affiliation - I'm just a satisfied customer of theirs), see the link in my signature for details... :tu:
Note: make sure you order the version for your car though (R170), not the one I ordered for mine (R171).
