I would give 5 stars for a more robust system and/or if this key locking system were about 20% cheaper. Easy to install, looks nice and minimal. Would I buy it again? Sure, but only for a phone charger not an iPad. I havent had the need to charge them at all since getting them. Customize Mounting Height as You Want. had my previous strobe not thrown off brighter and crisper light I?d probably be ok with this one. They were well made and the sizes fit perfect. -The head band is large. The control on ear so touch it will drive u batty at times. These sandals came quickly and in good condition.
