******************UPDATE 09/06/2018********************I have owned this for a year and a half and wanted to share my experience. It has performed flawlessly thus far and has been a great addition to our kitchen . The self cleaning process works like a charm. We needed to replace one of the bulbs and the customer service was very responsive in that process. It is low profile and looks gorgeous. Highly recommend!**************************************************************Original review:We are very pleased with the Tatsumaki TA-400 range hood. I am generally a conservative shopper and usually don't buy products with fewer reviews. However, we took a leap of faith with the TA-400 because: 1) we were looking for a powerful hood as we cook a lot of South Asians spicy/flavorful food (desirable) using a lot of frying and high heat cooking that make our entire home (and clothes) also smell flavorful (not desirable!) – especially in the winter; 2) we wanted ease of cleaning; 3) we preferred a low profile design; 4) we needed rear vent option as we were replacing an over the range microwave that was venting outside through the rear and all ductwork was already in place; and 5) we were on a budget! The TA-400 met all of those criteria. I am not an expert or super handy, but I will do my best to share my perspectives. I also don’t always take the time to review our Amazon purchases (mainly because we buy things that have already been extensively reviewed), but in this case, I decided to write in support of a less reviewed product.Shipping and Installation:• Shipping was fast, packaging was good, all accessories were in place.• The venting options were nicely laid out (came with top round vent, top rectangular vent and rear rectangular vent. We use the latter.• Installation was easy. We had a local electrician assist us. We took out the existing microwave, adjusted the rear opening of the wall to fit the Tatsumaki (simple expansion of the slot on the wall for the adapter to fit in). It mounted securely under the cabinet on top. We finished by adding backsplash to cover the exposed wall at the back (microwave was bigger!).• Three things to note: 1) It comes with open electrical wires for direct connection, but our microwave was plugged in. Our electrician installed a plug to the wires; 2) We were unsure about what to do with an open water line (for self-cleaning). A quick call to customer service informed us about the little hole through which that should be channeled; and 3) Since our duct routes through the garage into the attic and then outside, we took the baffle out of the adapter. The CS person mentioned that most client complaints about rattle type noises resulted from the baffle hitting duct or something. With no baffle, the sound is uniform.Performance:The performance of this 750 cfm range hood is awesome! You can select six speeds. It starts at 3 by default and you can toggle to higher or lower speeds. We used 3 for simple frying: eggs, hot dogs and such. We used 4 or 5 when we reheating food on the stove and 5 or 6 when cooking curry type dishes or fried stuff. In all cases, the strong smell that used to linger in our home is gone. There is a faint smell of food in the living/dining room that you would normally get if you serve hot/steamy food. What amazed us is that even the clothes we were wearing while cooking didn’t catch much smell. The self-cleaning process is a nice additional feature that seemed to work well during the one time we have used it so far. The hood is not whisper quiet and we didn’t expect it to be while moving air at 750 cfm. It is, however, less noisy than our microwave vent at high speed and the sound of the fan is very even and not harsh. We couldn’t ask for more in terms of performance.Critique:The only critique I have is about documentation. It came with documentation for TA-195/TA-395. Hence, there were no instructions about the self-cleaning system and installation of the water line. The Tatsumaki CS told me that they were experiencing delays in the production of instruction manuals of TA-400.Customer Service:While installing, we had the question about the open water line. I called Tatsumaki CS and Calvin picked up right away (no recorded message, no wait and no international call center!). We exchanged pictures via iMessage and the problem was solved. I later spoke to Calvin a couple more times (regarding baffle, self-cleaning process, etc.). He either picked up right away or called/messaged back within a reasonable time frame. I am not sure if it is a one-person show for now and how this level of service will sustain in the long run, but for now this has been the most attentive customer service I have ever experienced.Final words:We were a bit skeptical about the absence of full size vents and came with the two fan-like vents. We think it looks pretty good after installation in our kitchen, but you can form your own opinion from the pictures we posted. We have been using it for two weeks and are very pleased with its performance. We look forward to smooth performance and high quality service going forward.
