Came in skeptical, but it's GREAT!
I read all the bad reviews I could on this thing and considered it an acceptable risk considering the price. Assembly was easy and the instructions were fair. Not amazing, but once you handle the edger, the gist is clear. I was skeptical overall that the horsepower and plastic guard weren't going to be enough. I ran it for nearly 45min stopping every 5 or so to check the blade and guard. It stayed tight and I was able to manually turn the blade to make sure it was working right. My front yard and sidewalk have been neglected for a few years. I would sometimes edge it out with the weed Wacker, but couldn't get it as clean as I wanted without breaking a LOT of line. When I was done, I noticed the guard had a lot of soil and grass buildup that I was able to take out easily with my fingers. There were a few times I scraped the sidewalk edge, but the blade is still solid and ready for more! I was surprised at the quality and as you're going over an area, it feels solid and not squirly or out of control. My uses are going to be mostly suburban maintenance on my own yard. If I had more land or something bigger, I would consider something larger. For my yard and purposes, this edger is going to work just fine! Did not notice any issues with the blade getting loose, but stayed aware of it. There is a lock nut that keeps it in place. I imagine over time and switching blades, this is going to lose its locking function, but I already see amazon has replacement blades that come with new lock nuts!

Works great, easy assembly and no issues!
Using the weedeater for edging was too hard, so I purchased this. It works great! It was easy to assemble and easy to use. My lines are perfect, but the size, durability, and power of this gem get the job done, and it's lightweight enough that I can easily maneuver it around the yard. I chose a corded one so I don't have to deal with battery life or charging.

Excellent Kindle for reading every day
I’m very happy with this Kindle Paperwhite. The screen is easy on the eyes, even for long reading sessions, and the front light makes it comfortable to read day or night. It’s lightweight, the battery lasts a long time, and it’s super convenient to carry around with a whole library. Great purchase overall.

A great device with some minor issues
In a nutshell, kindle was created to give a comfortable reading experience, and it does a great job on that front. I feel like other aspects of the device were compromised. Good: - The screen is very clear. It feels like I'm reading from a real book - but with clearer text then I've seen in any real book. - There are no distractions. This is a very big advantage over reading from the free app on my phone, where I constantly find myself pausing from the book to check up on one thing or another. - The screen is wider and shorter than a standard phone. I find this to be much more comfortable to read from. Bad: - The device is sluggish. - The scrolling isn't continuous like on a smart-phone. - At 6'', the screen is smaller than most modern phones (but it doesn't feel small when you read from it). - There's no option to change the page color. - There's a limited selection of inbuilt fonts (but it's quite easy to add new ones). - The charger is the old micro-USB, and not the more modern USB-C. This means that I can't charge it from my phone's charger. - The screen is not colorful. I think this makes the book covers look bad. - Kindle is surprisingly stingy with memory. Considering how cheap flash drives are, I'd expect that kindle would either provide us with more memory, or at least make it cheaper to upgrade (it's currently about 100$ to upgrade to 32GB, when a 64GB flash drive is 10$).

Perfect device for reading
Bought it on prime day 7th Aug 2021. Used it for two months and it functions very well. Pros: 1. Clearly seen under the sunshine - I usually bring it out to the balcony in my office for reading. At first, I didn’t really see the difference from the iPad. One afternoon, I found it surprisingly performed very well even under sunshine. I can see every single word clearly under a sunny day. 2. Slow reaction but enough for me - It's the 2018 version so of course, it is slow in reaction compared with smart devices nowadays. But it doesn’t matter because I don’t read fast either. 3. Support my own documents - It also allows me to transfer my own documents to the device which is very convenient to me. 4. Built-in light - I can read at night! Without hurting my eyes. 5. Lightweight, thin - Super lightweight, I can hold it with a single hand without pain or put it into my small handbag, bring it to my office, read novels on the train/bus… 6. Long battery life - I usually turn it to airplane mode while reading which saves a lot of batteries. Can’t think of any cons so far. A 100 score device considering it’s a 2018 product!
