Customer Reviews
Reliable products every time
This isn't my first purchase from Boldr; I've bought several items over the last year, including a Kelvin heater and some Smart Thermostatic Valves. This time I got a Smart Home Starter Kit. I keep coming back because their products are consistently reliable and perform well. The setup for the new kit was just as smooth as my previous experiences, and all the devices integrated seamlessly with the app I already use. It's nice to know what to expect in terms of quality and ease of use. They haven't disappointed me yet.
Works great, quick delivery
Ordered a Klima Smart Thermostat. It arrived fast. Installation was simple. The app is easy to use. Happy with the purchase.
So happy with my heater!
I just got my Kelvin Smart Infrared Heater and I love it! The setup was so easy, and it works perfectly with the app. My room feels so cozy now, and I can tell it's way more efficient than my old heater. I'm already planning to get another one for my office. Definitely recommending Boldr to all my friends!
Detailed feedback on my order
I purchased a Smart AC Controller and a Kelvin Floor Stand recently. The ordering process on the website was straightforward, and I received a confirmation email immediately. Delivery was pretty quick, about 4 business days, which was good. The AC controller was relatively easy to set up with my unit, and the app integration works well, letting me control it from my phone. The Kelvin Floor Stand feels sturdy and was simple to assemble. I did have a small question about linking the controller to my smart home system, and customer support responded to my email within a day with helpful instructions. Overall, the quality of both items seems solid, and they perform as expected. I appreciate that the instructions were clear and not overly complicated.
Good value bundle
I was looking for a way to cut down on my energy bill and the Smart Home Energy Bundle caught my eye. The price was pretty good, especially with the bundle discount. I saved about $75 compared to buying everything separately. Shipping took about 5 days to reach me in California. The products seem well-made, and I'm hoping to see the savings on my next bill. So far, it feels like a worthwhile purchase.

Share tips, ask questions & help fellow shoppers save more
Does anyone know if the Kelvin heater comes with a stand or do you have to buy that separately? Trying to figure out my total cost.
Hey, thinking of grabbing a Kelvin heater and maybe a Klima controller. Do these things actually save you money on your electric bill or is it just marketing hype?
