Won't leak.  Pretty good.
The majority of these bottles did not leak IF the cap is screwed on tight enough.  Even when pressurized, so these are OK for airline travel without creating a mess, which is good.  That is hard to find, so kudos there.  Overall quality is OK for the price.  When dispensing, most product dispenses through the spout, but some can emerge beside the spout, so not quite as neat as some others I have used.  Plastic is stiff and hard to squeeze.  Seems durable and will serve its purpose for a long time.  Great price.
