Atomberg Renesa+ 1200mm 28W BLDC Motor with Remote Energy Saving Ceiling Fan (Earth Brown)

I have done a bit of research before buying this. BLDC is the same technology use to drive electric scooters, you might have wondered how such small battery can run the scooter for several kilo metres. Yes, it's all about power saving and that 's the BLDC motor. I bought two of this model and a cheaper Gorilla model too. So total i have 3 fans running for last 2 months and here is my review based on that. I know, my reviews are always lengthy, but sorry for that.The good# These fans are super power saving(28W) compared to traditional fans(75W) and modern power saving fans (50W)# Wind throw is more higher than the regular fans and much higher than power saving fans# The fan can be controlled by remote# Needs no regulator to operate (You can't use regulator even if you wish to)# Any Gorilla fan can be controlled by Any gorilla remote (Different models too)# Sleep mode, reduces speed automatically every 2 hours# Off timer (1~6 hours)# The LED in middle serves as night lamp# Even if you miss the remote, you can control speed easily using switch(Only in higher variants)# Looks so super stylish# Even lower energy consumption when used at low speeds# 3 years warranty, can be extended for one more yearCons# Is lightweight and has very minute wobbling# One of the fans i bought was buggy that the speed keeps going down and up when put in speed 5.# This model attracts more dust compared to Efficio models (Don't know why)Is it really costly ?No. I can give you a simple calculation to prove it. An average person uses a fan 12 hours a day, which means a saving of 0.565 units daily compared to a 75 watt fan. (75-28)*12 = 565. Yearly you can save around 205 units of electricity, which means roughly 820 Rs a year (Assumed cost per KWH is 4 Rs, which is the minimum. In cities it's higher than that).Cost of a good ceiling fan = 2500 RsExtra electricity consumed = 820 RsCost of a regulator = 300 Rs (I saved 600 Rs as my boards are Panasonic)Total cost for first year = 3620 RsPrice of Gorilla fan = 3800 RsSaving from second year = 820 RsSaving from third year = 820 Rsetc . etc. .It's a fact that ceiling fan is most energy consuming device in every family, which many people are not aware of. 12 hours a day, a normal fan means, 0.9 units a day. If you have 3 rooms, 2.7 units a day. If you can change 3 fans to Gorilla fans, you can cut this to 1 unit a day for all the 3 fans.Are DC fans reliable?I have a mixed opinion here. My friend has been using a Super fan for few years now and Gorilla fan for an year now and he has no issues yet. But one among the 3 fans i purchased has a buggy firmware, now i have to replace it under warranty.How Good is the wind throw?The wind throw is better than a normal 75 watt as per the specs and real world tests. I remember the specs says 240 CM compared to 220 and 230 offered by popular brands.Should i buy this model or a cheaper model?I recommend this fan for living rooms and main halls only. For bed rooms you can go for cheaper Efficio model as it has less options and hence maybe more reliable. Efficio doesn't looks so good and the remote is bigger. I didn't like the Red LED compared to blue one on Renessa+Should i change all my fans at once?No. Don't do that. Atomberg may launch more better and optimised models in the future. So start changing with those fans which you use the most.Overall, i would highly recommend this fan to anyone who is planning to buy a new fan. Please don't compare the fan price with the super cheap ceiling fans as they are not durable and use cheaper materials. I remember one of my friends had 4 cheap luminous models and all of them were dead in less than 5 years of usage. So buy either Atomberg or Medium priced good brand fans only. Definitely DC fans can cut down your electric bills dramatically, i assure. You can start with one or two fans.

The fan has been in use for just a little over a month. Mostly, I have been very happy with this product.Here are some observations:A. The positives:1- it's super easy to install, as there are just two wires (phase in, neutral out) to handle in the motor, and the rest of the process is illustrated stepwise and diagrammatically on the package box as well as the instruction manual.2- The precautions being asked by the manufacturer MUST be adhered to for the best performance from the product. Three things are asked clearly:•bypassing the usual external speed-regulator fixed on the switchboard. (The fan has it's own advanced speed control inside the motor assembly, it needs full power input at all times to function normally, it is still designed to consume less than half the power of a conventional ceiling fan.)• fixing of the fan's down-pipe ceiling-end assembly directly and firmly to the ceiling, without any intervening 'S' type suspender, etc.• fixing of the fan has to be firm, all nuts used need proper tightening (or it can be a safety hazard if any fan ran nuts!)3- the functions work just as claimed by the manufacturer, and they are a clear value-addition to this fan.The remote control is super; Innovative LED function as a fx. indicator and night light is neat (like many other users have already noticed, it would be great if they changed the hue to yellow-lamp one in night-light mode, this will be a slick utility addition to the product); timer is again a great utility and so is the sleep fx. specially in colder regions or such areas/weather where temperature drops after midnight.Antidust paint does help somewhat. After a month there is just a little hint of dust on the edges of the blades (again regular cleaning has to be done as per directions of the manufacturer for product life and performance)4- Mostly, if the fan works perfectly, the only noise audible is that of the shearing and driving of air down as it revolves. So it's motor makes no humm that's audible on the ground. Just the air being channelled through the blades, can be heard. And that sound will increase as the speed will increase. If a room has echo effect in it, it may sound a bit high. So, the fan motor in and of itself, does not seem to be making noise.5- the circuitry operating voltage range is also great, which is really a plus if one lives in poorly regulated inline voltage with frequent fluctuations. It works fluently while everything around stutters to the whims of those unpredictable and uncontrollable changes.6- the fan speeds are very properly scaled. That alone will make it so useful in most parts of India where celing fan is required (that means everywhere nowadays, even in Himalayan regions!)7. Airflow is just great. Another careful design change to the blades can widen it further outward. Presently, its strong vertically underneath the motor, and moving away from the range of the blade, there is a palpable drop in air flow. This happens in most fans. There is air at the edges of the room to be comfortable, but one wishes it were more.So it's about taking the same the airflow and rendering the distribution directionally even. It's still great as it is. And I think the next version of this fan will only optimise the radial flow coming out of the edges.(To address both the air flow noise and radial-out air-flow towards the edges, considering a 1400mm blade version may help. It will take down rpm to reduce airthrow noise while retaining/bettering the airflow volume but will also provide more blade surface area to work with air flow distribution profile. Just a thought.)8. It's design is novel! Very few fans will come close to it there as well.Overall, on the positive side this is a good value product. And more value can still be added to it. So there is a future surity built into the concept of this fan which makes the purchase really worthwhile.Kudos to the Atomberg team for creating such sleek and slick beauty!B. Now that this is a sure fire winner, let's look at aspects to work on:i. The 'click' sound being reported is gradually noticable on my unit as well, and there is also a vibrating/fluttering sound from the blades. I suspect the 'rivets' on the blades need another look. Especially as there is a slight wobble no matter how good the fix to the ceiling is. So that is a worry as it unnecessarily confuses many users on an otherwise great product.ii. The website needs to show product purchases made from any site as soon as a user registers for an Atomberg a/c and provides a legitimate unit-number no matter what source it was purchased from. That will be the best professional practice. If there is a genuine proof of purchase recognised by Atomberg, then that unit's purchase upon creating an a/c on website and registering the serial no. needs to be acknowledged in the users Atomberg product ownership page.iii. I haven't yet asked for customer care assistance but this is again a worry till now. How to get the issued resolved locally. There's a customer care number. But how will actual support be provided at my location, it still has to be looked into.I am keeping best expectations from Atomberg.I think this product is a winner. Now it's a matter of refining and enhancing its performance to perfection.

Review after 16 month,Very good product,good air flow, energy saving,LED like night lamp, remote controller function also good.
