UPDATE: 5/16/2018First off, let me state that I never got the L Series fan. Instead I ordered an H Series fan directly from Haiku which is great, although I didn't get the optional light kit which is standard with the L Series. Overall, it's the same functionality as the L Series except that the H Series is considered an upgrade due to the blade material and the color options. After seeing the components which make up the H Series and comparing to the L Series, there are more similarities between the two than they are differences.After experiencing my Haiku fan for a year, I recently purchased 2 more. These fans are solid and don't wobble at high speeds like other fans do. You can crank this puppy up and feel like you're in a wind storm and yet the fan will not wobble which I love.Another really nice aspect of the Haiku fan is the integration with the Nest thermostat. The fan and thermostat will work in conjunction with one another and adjust the use of the HVAC system by increasing the fan speed to maintain the desired temperature. This feature alone will save you money in the long run and will reduce the overall cost of ownership. I am not familiar with other ceiling fans which have this capability.The fan has a lot of other nice capabilities that others have mentioned in their reviews, but by far I like the way the Haiku fan integrates into my smarthome system and interoperates with Alexa and my thermostat. Mine has been up and going for almost a year now and I can't think of any issues that I have experienced since installing.One last item - it's an awesome looking fan once it's mounted.=========================================================================================================Update July 7, 2017: Unfortunately I have decided to return the fan as I just don't believe that this version of the fan is worth the cost for many of the reasons that I pointed out, but primarily due to my concerns of the materials used in this version of the fan. I may be totally off base so please don't base your decision to purchase or not on my incomplete experience. It may be a great fan, but the cost barrier is hard for me to overcome.I personally believe that Haiku could have done a better job in the durability of certain fan components. If for no other reason than perception to overcome the price shock. Much of the hype on the Haiku website and in reviews outside of Amazon appear to be referring to upscale versions of this fan such as the H series.=========================================================================================================Initial review: I am probably being somewhat unfair writing a review before even installing and trying the product, so I will preface my review by saying that it is based on initial impressions only as I sit here and ponder if I should pack it back up and return it or if I should give it a chance by going ahead and installing knowing that there is a strong possibility that I will be disassembling and returning.My first observation as I unpacked the fan is that the materials used in the L-series fans are OK, but not at all impressive especially given the cost. I don't see any craftsmanship here as it's all appears to be nothing more than injected plastic except for the motor, downrod and some miscellaneous small parts. While the plastic fan blades appear durable enough, the housing and casing not so much. After installing and looking at it from a distance, this could end up being a don't care for most people including myself. However, as I look at my $700+ order (the non-white/black blade option was an additional $75 to the base $600 and then taxes adds additional cost) still in its box I just don't see the cost benefit.I really agonized over this order given the cost of the fan. Yes, it's a great concept that no one else to my knowledge has yet exploited. However, is it really worth the cost? Especially for this plastic version of the fan. Based on the photos that I have seen on the Haiku website, it is an attractive fan, but then are so many other fans available at half or less the cost and quite frankly appear to be made of better materials.I did have a lot of questions and did review all the material available on the Haiku website and even contacted the manufacture and got a lot of questions answered and misinformation from other reviews cleared up. I will mention that I never got responses to 2 e-mails I had previously sent before contacting Haiku directly, but was finally able to get some questions answered via Haiku's online chat. Not getting any response to your e-mails concerning a potential high-cost purchase makes you wonder in the back of your head what the communication quality will be with the manufacture once you make a purchase.My online chat with Haiku did clear up most of my questions. However, not all of my questions were answered satisfactorily. BTW - there seems to be a bit of confusion in some of the reviews of the cost difference of the fans on Amazon vs. the Haiku website and the wifi module being included or not. The fans on Amazon are $50 more than the Haiku website, but that is because the Amazon version comes with the wifi module while the version on the Haiku website does not. The wifi module is required if you want to integrate the fan into your smart home or Alexa or control using your phone. The base cost of the L-series fan on the Haiku site is $550 vs $600 on Amazon. To get the wifi module directly from Haiku is an additional $50, not $150 like some have stated in their reviews. I believe the reason for the confusion is that Haiku doesn't advertise the wifi modules on their website. Instead they only advertise the wall control unit which is needed if you want the SenseMe capability. If you order the wall control from the Haiku site, they also include the wifi module which is required for the wall control to communicate with the fan. Why Haiku doesn't advertise the wifi module on their website, I don't know but it does add to the confusion that potential buyers have. However, I was told that Haiku would sell the wifi module, instead of having to purchase the wall control if you requested. I was also told that the different blade color options available on Amazon were also available on request from Haiku directly for the same cost as advertised on Amazon. Only the black and white options are advertised on the Haiku site.I was actually going to order one of the H Series fans from the Haiku site one weekend, but their online ordering system seemed to be having a problem when I attempted to execute my order. While I did receive an e-mail a day or two later that Haiku was aware of the issue and invited me to complete my order by giving them a call - I didn't. Again, due to the high cost of the fan plus the fact that I need at least 3 fans so I put off ordering and did further investigation.Although I never came to a conclusion that the capabilities and the attractiveness of the Haiku fans justified their cost, I did finally decide to push forward and try one of the lower cost L-series fans off of Amazon. I decided to order from Amazon since I thought that it would be easier to return the fan to Amazon than Haiku should the fan fall short of my expectations. My direct communication with Haiku thus far falls short of my overall expectations. Another thing to mention is that the warranty is only a year on certain aspects of the fan, only the motor has a lifetime warranty which is pretty common with most fans. When I asked Haiku about this, I was told anything that was going to happen should occur within one year. While that may indeed be the case, one would think that the manufacture should then be willing to give customers a stronger warranty if the historical trouble data shows that the vast majority of product issues manifest themselves within a year.
