Currently the only two SL-X poles that are in use are in one of our work vehicles. There are about 8 window cleaners that have worked with them over the last 10 months and their feedback has been very useful.
We hope to take delivery of the first batch of official poles tomorrow afternoon (courier dependent!), hopefully by Monday of next week there will be a whole heap of clients who have been able to use them and will then be able to give you their opinion.
As regards the SL-2, I would not recommend it for domestic work,purely due to its modular design. Having said that there are several of our clients and many on this forum who use this type of pole on domestic work all of the time because of its low weight.
