Would buy again for sure

Was a bit skeptical ordering online but really glad I did. The item arrived in a sturdy box — nothing rattled or was damaged. Set it up in about 10 minutes and has been working perfectly since. Compared to what I saw in store I saved a solid amount. Will definitely be back.
