Just works
Bought this to replace my super basic apt thermostat because I was tired of constantly adjusting the temperature based on the time of day. I like to keep it low at night but crank it up a bit during the day to help save some money, but still keep it reasonable for my pup. Even though this is another fairly basic thermostat, I have found the features to be great so far. Was actually surprisingly easy to install and that you can change the temp based on 4 different times of the week day and the weekend separately. Just make sure to be careful and take pictures and or mark the wires on the old thermostat to make sure you wire it correctly. Yes, most wires will correspond to the correct label but you never know for sure. Alot of cheap a$$ landlords out there. Speaking of which, I called them to have the maintenance come out and install it for me since they said it was something they would do when signing the lease and even the day of but then maintenance calls back and says oh we dont do that because if something goes wrong you would be liable and we can't fix the A/C. I was like wtf that doesn't even make sense and just said fine I'll do it myself. Never installed one of these before and only okay at handy work but found this to be a simple and very awesome upgrade so far. Make sure to cut the power! Also, be careful and don't bend the wires back and forth, they will heat up and break off. Be gentle with the wires and take your time. Don't screw them down until you have everything inserted and leave some slack in the line so it doesn't go back into the wall where you can't get to it. Don't mount to the wall until you check to make sure it works. If you have someone else I would recommend having them hold the unit up while you turn on the power to the A/C or very gently hanging it off the wires(just know it could fall off) and then when your sure that everything works you could mount it. Look up a video on YouTube or read the instructions if your not sure. It's really simple and easy to install. Highly recommend this so far and will update again to make sure the temps and settings hold correctly. :)

Simple to Set Up and Works Well
This Honeywell thermostat is straightforward and works exactly as advertised. Setting up the 5-2 day schedule was simple, and it makes adjusting your home temperature effortless. The display is clear, and the buttons are intuitive, so even if you’re not tech-savvy, it’s easy to program. It keeps the temperature consistent, which has been great for energy savings, and the white design blends nicely into most rooms. Overall, it’s a reliable, no-frills thermostat that gets the job done.

Saving me a lot of money
I installed one in an out building with sensitive electronics that must be in a climate controlled environment but can go a couple of days without human presence. I'm in Florida and the heat and humidity are PUNISHING. I like it at 78 when I'm in there but 85 if fine when I'm not. I can leave without worries I remembered to adjust the thermostat. It automatically switches to 85 at 1 pm. You can program multiple temperatures multiple times of day, you can even program a weekend schedule and weekday schedule. Set it and forget it.

I’ve been using the Honeywell Home RTH2300B1038 programmable thermostat for quite a while now, and it has been a reliable addition to my home. The setup was straightforward, and the programming options make it easy to maintain a comfortable temperature throughout the week. I especially like the clear display and simple controls, which make adjustments quick and hassle-free. It has worked consistently without any issues, helping keep the house comfortable in both summer and winter. Even after years of use, it still performs exactly as expected. If you’re looking for a dependable, easy-to-use thermostat without unnecessary complications, this is a great choice.

Works great
Works great. Bought it as a replacement for the old one. Was exactly the same just cheaper in price than the one from Home you know where. lol. Works great. Controls the air conditioning and heat and you can get technical if you want to and set timers and all that but I just use it to turn on a/c and heat. Would recommend.

No separate heat and cool settings
This review is for the Honeywell RTH2300B1038 5-2 Day programmable thermostat. It works OK (meaning that it turns my furnace on and off), but it has several drawback that don’t match its higher price point over less expensive thermostats that have greater functionality. Installation was not quite as straight forward as I expected, I had to cross reference some youtube videos to make sure I was correctly leaving the blue thermostat control wire disconnected. A few extra details in the instructions would be helpful here. The first thing I noticed when it was connected and powered up is that it had the same dark/dirty area in the lower right corner of the green backlight that everyone else has pointed out. Definitely some quality control issues during manufacturing here. There’s a confidence booster… This isn’t really a big deal, because I don’t need to use the backlight. The next think I noticed was the deal breaker for me: though there is a five-day and a two-day program, there is only a single group of settings that will apply to BOTH the heating and cooling cycles. During the winter, we keep our furnace set a bit lower, usually around 67 degrees. During the summer, we keep the air conditioning set higher, around 75 degrees. You cannot achieve these setting with this thermostat - you only get one set of settings. This means you have to reprogram the thermostat every time the season changes. Call me lazy, but this introduces hassle that wasn’t present with my previous thermostat. This means I would need to write down the settings in some place that I’ll be able to find six months later. No thanks. The next thing that I noticed is that this Honeywell thermostat causes my furnace to cycle much more frequently than the old thermostat did. This results in more wear and tear on your furnace and air conditioning compressors. There might be a place to adjust this behavior, broadening the temp spread for the turn-on and turn-off points, but given that it only has a single set of time/temp settings, I had already made up my mind to return it, so I didn’t bother looking through the manual to see if this is possible or not. If you find yourself in need of a new thermostat, save a few dollars and pick up a Lux Pro PSP511C thermostat that is much better. It has separate time/temp setting for heating and for cooling and you can easily adjust the on/off temp spread so your equipment cycles less often. This saves wear and tear and is also more energy efficient.

Please check before you buy.
I found out to my cost that this unit will not switch 240v. This means, if you're trying to make your roomstat more intelligent, this is not the one for you. Thank you Amazon for a stress free return and refund.
