Not bad product but the glue is all over

Would Not Recommend

First time buying windows from Lowe’s Not bad made windows but the glass is covered with glue , took hours to clean it off. Sloppy workmanship Would not buy same windows again

Bad Quality

Would Not Recommend

7 of the 10 last windows I've ordered have either been broken or damaged. A lot of the vinyl welds were cracked. Windows ARE NOT sturdy. Cost is so far above quality. This is why "Made In The USA" products suck.

Solid for the price

Would Recommend

The window was perfect except for a tiny misaligned bevel on the frame part. It honestly might function as a weep hole.

No head expansion for stock.

Would Not Recommend

The window itself seems to a good replacement window, but why the supplier provides two sill extensions and NO head expansion.
