Honestly disappointed for the price point. The buttons are mushy and mine started flaking out after only three months of light use. Getting support to answer was a nightmare, might just switch back to a different brand next time.

Super easy to set up! My back didn't hurt at all the next day which is a first for me with air mattresses. 5 stars.

Excellent value for a basic kitchen appliance. The build quality is decent for plastic, and the browning levels are accurate. If you need a simple toaster that doesn't hog the whole counter, this is it.

These are way easier than the standard gel-x kits because you don't have to worry about painting the tip perfectly. The primer is already on them which makes a huge difference in how long they last. I'm on day 10 and no lifting yet.

I bought these for a table project and they worked great! The quick-release is super smooth and they feel way sturdier than I expected for a 4-pack. Definitely worth it if you're just starting out

I finally upgraded from a plastic board and I'm never going back. This walnut wood feels so premium and it's huge enough to chop a whole roast on without making a mess.
